Although almost every other major religion out there acknowledges that Jesus really did live, there are still people who insist He is a fairy tale, like a mythological legend from ancient history. Or they believe that He was a real man but never claimed to be God, that His followers made it up after He died. And many believe that the Bible, though a good book, was written just from men’s minds and wasn’t really God-inspired.
When trying to reason with people like this, many Christians quote Bible verses to try to win the argument, thinking it should convince everyone of God’s Truth. But since many people, including atheists, don’t believe the Bible is true, they don’t want to hear the Bible being used to try to prove the validity of the Bible. That’s “circular reasoning,” using the Bible to validate the Bible. This is why it’s important to have sources outside the Bible that confirm that Jesus really did live and that Scripture is really reliable.
And if Scripture proves to be reliable, then we need to take Jesus’s claims that He is the Christ, God in the flesh and the only way to heaven, much more seriously. Because, yes, He Himself did claim these things. We can choose to not believe Him, but we cannot deny that He claimed it.
John 10:30,14:6-9: “I and the Father are one… I am the way and the truth and the life. No one comes to the Father except through me. If you really knew me, you would know my Father as well. From now on, you do know him and have seen him… Anyone who has seen me has seen the Father.”
In Matthew 16:15-17, Jesus asks Simon Peter “Who do you say I am?” And Simon Peter answers, “You are the Christ, the Son of the living God.” And Jesus doesn’t deny it but confirms it. “Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven.”
In John 8:56-58, Jesus claims that He saw Abraham, who lived many centuries ago. And when the Jews question Him (“You are not yet fifty years old, and you have seen Abraham!”), He replies, “I tell you the truth, before Abraham was born, I am!” This is Jesus clearly calling Himself God because that’s the name God gave Himself when He sent Moses to free the Israelites from Egypt. Exodus 3:13-14: 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.’” [I AM indicates the eternalness of God. He’s not I WAS or I WILL BE. He is always I AM because He is God.]
The Jews knew exactly what Jesus was saying. They knew He was claiming to be God when He called Himself “I AM” and when He said that He and the Father are one. They knew He was claiming to be God when He exercised His right to forgive sins in Mark 2:5-7: “When Jesus saw their faith, he said to the paralytic, ‘Son, your sins are forgiven.’ Now some of the teachers of the law were sitting there, thinking to themselves, ‘Why does this fellow talk like this? He’s blaspheming! Who can forgive sins but God alone?’”
And because the Jews knew what He was claiming, they tried to kill Him. John 8:59: “At this, they picked up stones to stone him, but Jesus hid himself, slipping away from the temple ground.” John 10:31-33: “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.’”
In fact, at the trial before Jesus’s crucifixion, he makes the clearest claim yet. Mark 14:61-64: “Again the high priest asked him, ‘Are you the Christ, the Son of the Blessed One?’ “I am,’ said Jesus. ‘And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.’ The high priest tore his clothes. ‘Why do we need any more witnesses?’ he asked. ‘You have heard the blasphemy. What do you think?’ They all condemned him as worthy of death.” And the Jews finally got their way. They couldn’t kill Him the other times they tried, but they did get Him crucified. Because they couldn’t believe He was telling the truth, that He really is God.
Like I said, you don’t have to believe Him either, but you do have to admit that He claimed to be God. And if the Bible proves to be a reliable document, you need to answer this question for yourself: “Who do you say Jesus is: the Christ (God in the flesh, the only way to heaven) or just a man, a blasphemer?” (And if you decide He’s just a man, a blasphemer, what happens if you’re wrong?)
So what I am going to do here is give a quick overview of some extra-biblical support for the existence of Jesus and the validity of the Bible. This is my paraphrase of information mostly from Lee Strobel’s book, The Case for Christ (he was an investigative journalist who set out to disprove the resurrection of Jesus, but ended up believing in it instead) and Josh McDowell’s book, Evidence that Demands a Verdict (he was a pre-law student who didn’t want anything to do with Jesus or “religion,” as he called it, but he was challenged by some Christians to research the resurrection to see if it was true, and he accepted the challenge, confident he would swiftly and surely disprove it. He even dropped out of college for a time to do research in the great libraries of Europe. But as result, he came to believe in the resurrection instead and that Jesus is who He said He is.).
