The Three Israels – Part 1: Biblical Israel

The Three Israels – Part 1: Biblical Israel

In light of current events, (and the overwhelming ignorance of certain politicians in our country who claim to be Bible-believing Christians) it seems pertinent to share a set of three sermons I preached during the Autumn of 2023, on the Biblical, Historical, and Modern meanings of the name “Israel.”

As the title suggests, this first message deals with “Biblical Israel.”

If you prefer – the audio of this sermon can be found at the following SoundCloud link:

This audio version was originally written and preached for Dailey Chapel Christian Church, on October 15, 2023. The following transcript has been minimally updated since then.

_____________________

Last week when Nelly and I arrived at church, we were not aware of the horrific situation that had been unfolding in Israel since the day before – October the 7th. And that’s my fault. Over the past few years, I have intentionally cultivated the habit of not watching the news very often.

And that’s just been a personal decision for me, since I discovered a few years ago that listening to, or watching the news, on a regular basis, was adding more anxiety to my life than I wanted to manage. But we do watch the news, at times, if we really want to.

We don’t have network television or satellite TV in our house. We get everything we watch through streaming services, so that makes it really easy to not even accidentally watch the news – because we’re not flipping through channels. And last Saturday night, we had gone to the music festival out at the Wheat Ranch, and then we came home and ended up watching Back to the Future III before going to bed. So, we didn’t know what happened in Israel until it was mentioned during prayer request time here in church the next morning.

And even then, we didn’t know the scope of it, until we left church and looked it up online. We only knew what was said – that there was a terrorist attack in Israel.

And, not to be callous, but I just figured it was business as usual, before we looked it up. Terrorist attacks are part of the cultural environment over in that part of the world – they happen all the time, and they are always terrible, but we weren’t expecting it to be anything as bad as it actually was and is.

So anyway, I bring all this up, for a couple reasons. The first one, is that when this kind of violence occurs in the Middle East, and brings the State of Israel into the forefront of the news cycle, it tends to generate some questions and maybe even a little apprehension among us – and rightly so. A handful of us were already talking about it in Bible Study this past Wednesday.

As Christians who study the word of God, and believe the history that we have in the Bible, we know and recognize that just the name “Israel,” itself, is an important name. So, when the whole world is talking about Israel, we’re going to be talking about it, or at least thinking about it as well. As followers of Jesus Christ, we cannot escape our connection to the name Israel.

Secondly, the reason I bring this up, is because the particular section of Romans that we’ve been working through these past few months, mentions the name Israel repeatedly. The name Israel appears twelve times in chapters 9, 10, and 11 – and if we include pronouns referring to Israel, or related terms and synonyms as Paul uses them – such as “Israelite” and “Jew” – then it’s more like 30 times, or more, that Israel is mentioned. As we already know by now, Israel is the main subject of this middle section of Romans.

So, for these reasons, and because of the terrible events that have occurred over the last week, and which I’m sure will continue to unfold into the foreseeable future – I think it would be prudent of me to spend some time defining exactly who and what we are talking about when we read about Israel in the Bible, as well as when we hear about Israel on the news, or when we bring up the name Israel in conversation.

It’s extremely important for us to understand. It’s a complicated name – it’s an emotional trigger word (both good and bad) for millions of people in the world, in the three big monotheistic religions – Christianity, Judaism, and Islam. And it’s important for us to understand how the name Israel is used in the context of the Bible, how it’s used in the context of history, and how it’s used in the context of current events that are taking place.

So that’s what we’re going to talk about today. We will begin talking about it. It’s a little too large of a subject for just one Sunday morning. But over these next few weeks, we’re going to talk about what I call – the Three Israels.

I’m sure there are professional historians who would lambaste me for making these three distinctions, in this way. There’s a lot of Jews who would probably take issue with these labels as well. But this is how I think of them, based on what I’ve learned, and I think it’s an easy way to keep them categorized for the purposes of discussion – especially while we’re unpacking the conclusion of Paul’s discourse in Romans 9, 10, and 11.

The Three Israels are: Biblical Israel, Historical Israel, and Modern Israel.

Are they all the same? Are they all different? Can each of these manifestations of Israel be completely separated from the others, or are they inseparably tied together? That’s what we’re going to explore.

And, believe it or not, the text of Romans Chapter 11, just so happens to be, a great place to explore these questions. So, we’ll be working Romans 11 into this discussion of the Three Israels as well, which will have the added bonus of moving us along in our study of the letter, and concluding this second volume of Totally Righteous.

Let’s begin with Biblical Israel.

This is the Israel that we should all be pretty familiar with already. We talk about it every week in church. Anytime we read the Bible we’re dealing with Biblical Israel, because that’s who God revealed the Scriptures to – from beginning to end.

Biblical Israel is first mentioned in the Book of Genesis, Chapter 32, verse 28. Israel was originally the name of one man. His name was Jacob. He was the grandson of Abraham, a man defined by his faith, who God handpicked to be the father of many nations. God made an agreement with Abraham to bless him, to bless his descendants after him, and to one day, bless all the nations of the earth through his family bloodline.

That promise carried over to Abraham’s son Isaac, and then to his grandson Jacob. Each of these men, father, son, and grandson, all had defining moments in their lives, and Jacob’s defining moment was when God changed his name to Israel.

God came down to earth, took on the form of a man, wrestled with Jacob face to face, and then pronounced that his name was no longer Jacob, but Israel – which means: “he who struggles with God.” God seared this new name into this man’s mind by creating an experience for him whereby he actually physically struggled with God.

However, the name change was not just reflective of his immediate situation, but it was also an appropriate summary of Jacob’s whole life, and how he had spent years struggling with God relationally.

And that pattern that was characteristic of Jacob’s – now Israel’s – life, would also come to define the pattern of his descendants as well. God chose that name for His people, knowing that they would have an ongoing struggle with Him, relationally speaking. Every generation born from the house of Israel would have to struggle with their collective relationship to God. We’ve talked about this pattern before – it’s the cycle that we see unfold through the rest of the Old Testament, as one generation after another is born, takes their place in the history of God’s people, and is ultimately defined by their relationship to God.

They followed that revolving cycle of peace and prosperity in God’s grace, followed by idolatry and immorality and turning away from God, followed by God’s judgment and discipline, followed by humility and repentance, and then followed by God’s restoration and redemption for them. That’s their collective struggling with God happening over and over again, through the pages of the Old Testament and into the New.

Despite this struggle, or perhaps because they continued to struggle WITH HIM, rather than WITHOUT HIM – God blessed them, guided them, delivered them from slavery, and protected them as a nation of people. Even when they were almost completely wiped out, He preserved those who were faithful to Him. Even when they were forcibly ripped away from their homeland, He kept them alive, and He brought them back and re-planted them in their own piece of land.

Even in their darkest hours, when it seemed like there was no hope, God gave them hope. He sent them prophets to tell them that He had a plan. That there was always hope. Their suffering was only temporary. One day, He would send them a Son – the Prince of Peace, the King of Kings, the Lord of Lords – to establish a perfectly just and righteous Kingdom for all eternity. One day, God would fulfill His promise to Abraham to bless all nations of the world through him and his descendants.

When the story of Biblical Israel transitions from the Old Testament into the New Testament, it’s because the King had finally arrived. And one of his closest disciples and friends – the Apostle John – writes this about him, and says, in that famous passage of John Chapter 1:

He came to establish a Kingdom that would last forever. The story of Biblical Israel does not end when Jesus goes back to Heaven after his death and resurrection. The story of Biblical Israel doesn’t end, even when the credits roll in the Book of Revelation. The promises that God made to Israel extend for all eternity through those who believe in Jesus Christ, and will live forever. The promises that God made to Israel extend beyond the boundaries of this temporary life, and beyond the boundaries of Abraham’s bloodline.

This is what Paul says in Galatians 3:26-29:

It’s the same thing Paul says in Romans 9:6-9. To summarize and paraphrase – Not all those who are descended from Israel are Israel. Not all of Abraham’s descendants are his children. Abraham’s offspring, God’s chosen people, Israel, are those who have faith in Jesus Christ as Lord and Savior.

So, what’s that mean for this particular discussion? Well, it means that ever since Christ came to Earth and inaugurated his Kingdom; ever since he died, and rose again, and ascended to heaven, ever since the time when the Apostles were writing the New Testament, the scope of who can be accurately called by the name “Israel,” as defined in the Bible, has been changed.

The definition of Biblical Israel has been, in some ways, narrowed to include only those who follow Jesus. But in another way, it has been widened to include all those who enter into God’s spiritual kingdom through Jesus, no matter what race they are from – Jew or non-Jew. That is the definition of Biblical Israel.

Biblical Israel was founded physically under the Old Covenant, fulfilled spiritually in the New Covenant, and when Christ returns, the physical and spiritual will come together into one, and ripple out into all eternity. This is the Israel made up of all Jews and non-Jews who put their faith in Christ.

But this brings us to the next manifestation of Israel. What I call “Historical Israel.” There may be a better name for it. Paul would probably call them Unfaithful Israel, but we’ll stick with Historical Israel. In any case, since the birth of the Church, there has been another Israel, made up of those who did not put their faith in the Messiah.

One of the things that makes Paul a little hard to follow at times, in Romans 9, 10, and 11, is that in the midst of his theological discussion about Israel, he is going back and forth between these two Israels. He doesn’t refer to them specifically as two different Israels, but that’s what he’s describing – the idea of a faithful, Biblical Israel, and an unfaithful Historical Israel.

Historical Israel is the nation of Jewish people that continued on after the birth of the Church, the vast majority of whom had rejected Christ. That’s the problem that Paul is unpacking in this section of Romans. So many of his fellow Israelites had failed to live up to their full potential because they rejected Jesus, and Paul, as an Israelite who had accepted Christ, was greatly disturbed by this tragedy.

In Romans Chapter 11, after addressing the root of the issue in the previous two chapters – which is faith verses unbelief to summarize it as concisely as possible – Paul then addresses both faithful and unfaithful (Biblical and Historical Israel) at the same time. And this is what he says to them, and about them, in Romans 11:7-10:

So, this is Paul stating, by the use of Old Testament references, that there is a difference between Biblical Israel and Historical Israel. The elect that he mentions are those who we could call Biblical Israel – those who received salvation through faith in Christ.

The rest, are Historical Israel – those who rejected the New Covenant, and sought salvation through human effort, which is not possible. They rejected Christ, and because of that, they called down a curse upon themselves.

Paul references this curse by quoting Deuteronomy, Isaiah, and Psalms here in Romans 11:8-10. He mixes three Old Testament verses together to refer to their collective blindness and suffering. But this idea of them receiving a curse for their rejection of Christ is, perhaps, a little more viscerally communicated in Matthew Chapter 27.

It was at the end of Jesus’ trials, just before he was crucified. Pontius Pilate was looking for any excuse he could find to release Jesus, without causing a riot in Jerusalem. Even his own wife told him to let Jesus go. But he was caught between a rock and hard place, so to speak.

So, in verses 22-25 of Matthew 27, Pilate brings Jesus out in front of the crowd and lets them decide. He says:

That is one of the most chilling verses in the Bible. The Jewish people in Jerusalem, yelling for Jesus their Savior to be executed, and so sure of their righteousness in doing so, that they were willing to call a curse down upon themselves and their children in the process.

Now, this curse that they called on themselves has been used, throughout history, by some, as a justification for anti-Semitism. So, I just want to say, emphatically, that it should never be taken that way. There is no justification for anti-Semitism, and any so-called Christian who has ever condoned violence and persecution and discrimination against the Jewish people, is not a real Christian.

As Christians, it is our duty to show Christ to all people through love and service. God still desires the reconciliation, of the historical people of Israel – and this is what Paul communicates as Romans 11 continues.

In Romans 11:11-12 he says:

He’s saying that there is still hope for those who belong to the historical people of Israel descended from Abraham – even as there is hope for all nations of people; for every person who calls on the name of Christ. They did not stumble beyond recovery. 

Redemption is still available. Historical Israel can still be folded back into Biblical Israel, if they accept Christ. And many countless individual Jews throughout history have done so.

Then, in the next set of verses, Paul talks to the Gentile Christians that he was writing to in the city of Rome. As far as we know, the Gentiles outnumbered the Jews in the Roman church, and some scholars think that the Gentile Christians needed to be reminded, and encouraged to not view themselves as superior to the Jewish Christians. Some scholars surmise that the Gentiles were getting a bit of a chip on their shoulder, and that they needed to have any notion of anti-Semitism squashed completely, before it could grow into something destructive. Which is why Paul says what he says in verses 13-21:

He goes on in verses 22-24 to summarize his whole train of thought:

There is still a chance for them. But unless, and until, they accept Christ, then they remain under the curse of their ancestors. Christ is the only way out of the curse, not just for them, but for all people. So, until they accept him, Historical Israel is not the same as Biblical Israel.

Biblical Israel is any Jew or Gentile that has put their faith in Jesus Christ as Lord and Savior. Historical Israel are the Jews who were cut out of the tree, but still exist, and for whom Paul had hope that some of them would still accept Christ and be saved as he had been.

So, there’s a branching off that occurred at that point in history when the Church was born. There were two Israels from that point on. So, the question is, what happened to Historical Israel after that time? What happened to the branches that were pruned off, and yet survived and carried on?

Well, we’ll talk about this more next week, and I mentioned it back at the beginning of this series, but just a handful of verses later, in Romans 11:28-29 Paul says about Historical Israel, that:

So, even though they rejected Christ in the first century, as a nation of people, they have persisted and thrived, despite being one of the most persecuted people to ever exist on planet Earth. Even though they may be enemies of the Gospel message, God loves them, on account of Abraham, Isaac, and Jacob, and He has not left them high and dry. So, what happened to them after the first century?

Well, to put it as simply as possible – they survived. They survived many hardships as a people group, in spite of incredible odds. Some of the history we know. Some of you have been around long enough to have seen some of the more recent history of the Jewish people. The rest of us learned about it in school when we were kids. But there’s a lot more than just what we know as the immediate history of the Jews. A lot happened in between the first century, and 1948 when a large portion of Historical Israel, coalesced into the third manifestation of Israel – the modern State of Israel.

I told you at the begging of this message we would talk about Biblical Israel, Historical Israel, and Modern Israel. And we will, but we just don’t have time to go into all of it today. Biblical Israel we’ve talked about, and I think everyone understands that this is the Israel we talk about every Sunday, or in every Bible study. This is the Israel that we are a part of – the olive tree that we’ve been grafted into as the Church.

Historical Israel, then, even though we’ve briefly defined it today, as Scripture defines it, as Paul defines it – there’s a lot more to say. As I said, there is a lot more history that many of us are not as familiar with, and I don’t want to brush over all that too quickly. It needs to be properly surveyed and discussed, because understanding Historical Israel, will help us understand how we get to Modern Israel, or the modern State of Israel.

And understanding how each of these three Israels are tied together, and how they diverge from one another, might help us make a little more sense out of the terrible things we see happening on the news – or at least help us understand what the name Israel means, and how different groups of people use this same name. The name Israel is important.

I said this at the beginning of the message, and I’ll say it again as I close: As followers of Jesus Christ, we cannot escape our connection to the name Israel. As those who have been grafted into the Olive Tree of Israel, we now carry with us the promise that God made to Abraham thousands of years ago. The Church is a part of what God views as His people Israel.

That means, that just as the name Israel was applicable to Jacob, and to his descendants, it’s also applicable to us as well. Who among us, can say with absolute honesty and certainty and sincerity that we NEVER struggle with God? I hope none of us say that.

We can still believe in Him, and remain faithful to Him, and still be obedient to Him, but also struggle with Him. He wants us to wrestle with Him. He wants us to go to Him with our problems and our anxieties, and our griefs and our confusion over things that happen in life. He wants us to go to Him with questions about why bad things happen.

He wants us to grab hold of Him and not let go until we get a blessing – the way Jacob did. Of course, Jacob’s blessing was a dislocated hip, but still, even that was a blessing that reminded him of his personal encounter with Almighty God. It reminded him of his name – HIS IDENTITY.

And we need to be reminded of our name, and our identity in Christ as well. Everyday. We’re all going to struggle. God wants us to struggle with Him, rather than struggling without Him.

If you’ve given up struggling with God. Now is the time to go back to Him.

The time is short. The days are evil.

But the Lord is reaching out and ready to receive all who call on his name.

If you’ve never believed in Jesus Christ, never put your faith in him, he is willing to meet you where you are.

Jesus Christ is God

I always look forward to those rare moments that come along where a random interaction with someone leads to a deeper discussion about something serious, or when a seemingly inconsequential series of events culminates into something that is extremely important, or when something that seems insignificant in the grand scheme of things, becomes the prelude to something with fundamental purpose.

I experienced one of these occasions this past weekend when I went to my cousin’s high school graduation party. After I walked in and helped myself to a fine brunch buffet, I sat down in the living room to chat with my older sister and my dad while we watched a slide show of my cousin’s life. There were several people milling about the house, and there was nothing really out of the ordinary at all. It was pretty much what you expect each year when these types of parties roll around. But within just a few minutes of my arrival, everything changed.

As I was sitting on the couch, discussing home remodeling issues with my sister, a guy from my home church sat down in another chair across the living room. I’ve talked with Rob before, and he’s a great guy who I’ve had a few good discussions with in the past. He loves to talk about God. I could tell as I was chatting with my sis, that he was waiting for a break in our conversation so that he could engage me in a discussion. Well, sure enough, as soon as I finished talking Rob began asking me questions. He began with the usual questions about school and what I was studying at seminary. When I told him I was studying theology and church history his eyes lit up and he immediately sent what can only be described as a barrage of theological questions my way.

Rob asked me some good questions, like who is God? And what is God’s name? I proceeded with a brief discourse about the trinity, to which Rob replied by asking me where in the Bible it talked about the nature of God. I quoted a few passages and then went on to talk about some of the erroneous views of Christ, as Rob asked me some more questions. The questions kept coming and the conversation continued into the next half hour or so. After we reached a point where Rob was sufficiently satisfied that he understood what I believed about God, he then informed me with a grin on his face that he did not believe in the trinity, and that he did not believe that Jesus was God.

To say that I was shocked at this information would not do justice to my internal reaction upon hearing this from Rob. I didn’t know what to say as Rob launched into a discourse that involved his misinterpretation of key passages in the New Testament. The whole time he was speaking, I kept thinking to myself, “is this really happening?”

Knowing that Rob was an influential youth group sponsor, not to mention a member of my home church, I couldn’t resist asking him if the elders of our church knew what he believed. He informed me that they did, and that they had told him they didn’t mind as long as he still believed that Jesus was the Son of God. I went home that afternoon in a haze of confusion, unable to make any sense out of the nonsense I had just heard from this guy that I really did have some genuine respect for, and to tell you the truth, I was even a little depressed by it all.  I felt kind of like I had stumbled into the bizzaro world from Superman, where everything is the complete opposite of what it’s supposed to be.

For anyone who doesn’t know, the deity of Jesus Christ as part of the Trinity is a fundamental, basic doctrine of Christianity, and has been since the inception of the Church. This is also referred to as the Incarnation, which means that Jesus is God come into human history in the flesh. It is the foundation of our entire faith. The scriptures are not vague on this particular issue; they are in fact abundantly clear. Even the Jehovah’s Witnesses, who do not believe that Christ is God, have been forced to produce their own separate mistranslation of the Bible in an effort to avoid the point that Christ is God. If Satan was only ever able to tell one single lie, somewhere at the top of his list would be the lie that Jesus is not God. Because if Satan can get someone to believe that, he can get them to believe absolutely anything. Let’s take a look at the scriptures, shall we?

Matthew 1:22 and Isaiah 7:14
“All this took place to fulfill what the Lord had said through the prophet: ‘The virgin will be with child and will give birth to a son, and they will call him Immanuel’—which means, ‘God with us.’”

Matthew 4:10
“Jesus said to him, ‘Away from me, Satan! For it is written: Worship the Lord your God, and serve him only.’”

Matthew 28:9
“So the women hurried away from the tomb, afraid yet filled with joy, and ran to tell his disciples. Suddenly Jesus met them. “Greetings,” he said. They came to him, clasped his feet and worshiped him. Then Jesus said to them, “Do not be afraid. Go and tell my brothers to go to Galilee; there they will see me.’”

Mark 2:5-7
“When Jesus saw their faith, he said to the paralytic, ‘Son, your sins are forgiven.’
Now some teachers of the law were sitting there, thinking to themselves, ‘Why does this fellow talk like that? He’s blaspheming! Who can forgive sins but God alone?’”

John 1:1-5, 14
“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it… The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.”

John 5:17-23
“Jesus said to them, ‘My Father is always at his work to this very day, and I, too, am working.’ For this reason the Jews tried all the harder to kill him; not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.

 

Jesus gave them this answer: ‘I tell you the truth, the Son can do nothing by himself; he can do only what he sees his Father doing, because whatever the Father does the Son also does. For the Father loves the Son and shows him all he does. Yes, to your amazement he will show him even greater things than these. For just as the Father raises the dead and gives them life, even so the Son gives life to whom he is pleased to give it. Moreover, the Father judges no one, but has entrusted all judgment to the Son, that all may honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father, who sent him.’”

Exodus 3:13-14 and John 8:57-58
“Moses said to God, ‘Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them? God said to Moses, “I am who I am. This is what you are to say to the Israelites: ‘I AM has sent me to you.’”

 

“You are not yet fifty years old,’ the Jews said to him, ‘and you have seen Abraham!’
‘I tell you the truth,’ Jesus answered, ‘before Abraham was born, I am!’”

John 10:27-33
“My sheep listen to my voice; I know them, and they follow me. I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all no one can snatch them out of my Father’s hand. I and the Father are one.’ Again the Jews picked up stones to stone him, but Jesus said to them, ‘I have shown you many great miracles from the Father. For which of these do you stone me?’ ‘We are not stoning you for any of these,’ replied the Jews, ‘but for blasphemy, because you, a mere man, claim to be God.’”

John 12:44-46
“Then Jesus cried out, ‘When a man believes in me, he does not believe in me only, but in the one who sent me. When he looks at me, he sees the one who sent me. I have come into the world as a light, so that no one who believes in me should stay in darkness.’”

John 20:28-29
“A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, ‘Peace be with you!’ Then he said to Thomas, ‘Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe.’ Thomas said to him, ‘My Lord and my God!’”

Acts 20:28
“Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood.”

Romans 9:5
“Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised! Amen.”

Colossians 1:15-20
“He is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.”

Colossians 2:8-10
“See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the basic principles of this world rather than on Christ. For in Christ all the fullness of the Deity lives in bodily form, and you have been given fullness in Christ, who is the head over every power and authority.”

Philippians 2:5-11
“Your attitude should be the same as that of Christ Jesus: Who, being in very nature God, did not consider equality with God something to be grasped, but made himself nothing, taking the very nature of a servant, being made in human likeness. And being found in appearance as a man, he humbled himself and became obedient to death—even death on a cross! Therefore God exalted him to the highest place and gave him the name that is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.”

1 Corinthians 8:4-6
“So then, about eating food sacrificed to idols: We know that an idol is nothing at all in the world and that there is no God but one. For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.”

Titus 2:11-14
“For the grace of God that brings salvation has appeared to all men. It teaches us to say ‘No’ to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age, while we wait for the blessed hope—the glorious appearing of our great God and Savior, Jesus Christ, who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good.”

1 John 5:20
“We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true—even in his Son Jesus Christ. He is the true God and eternal life.”

Hebrews 1:8
But about the Son he says, ‘Your throne, O God, will last for ever and ever, and righteousness will be the scepter of your kingdom.’”

2 Peter 1:1
“Simon Peter, a servant and apostle of Jesus Christ, To those who through the righteousness of our God and Savior Jesus Christ have received a faith as precious as ours:”

Revelation 1:8 and 17-18
“’I am the Alpha and the Omega,’ says the Lord God, ‘who is, and who was, and who is to come, the Almighty.’”

“When I saw him, I fell at his feet as though dead. Then he placed his right hand on me and said: ‘Do not be afraid. I am the First and the Last. I am the Living One; I was dead, and behold I am alive for ever and ever! And I hold the keys of death and Hades.’”

Likewise, the following sets of verses are places where the New Testament refers to Christ by the same designation used to refer to God in the Old Testament:

First and Last
Isaiah 41:4; 44:6; 48:12 – cf. – Revelation 1:17; 2:8; 22:13

Light
Psalm 27:1 – cf. – John 1:9

Rock

In summation, there is this thing that we Christians believe called the doctrine of the Trinity, which in short means that there is one God, revealed to us as God the Father, God the Son, and God the Holy Spirit.

For anyone struggling to better understand the doctrine of the Trinity, I would recommend a reading of Mere Christianity by C.S. Lewis, wherein he devotes several chapters to the subject. His discussion of the Trinity helped me a great deal at a time when I was searching for more clarity on this doctrine.
