Answer: Unlike the question “Does God exist?” very few people question whether Jesus Christ existed. It is generally accepted that Jesus was truly a man who walked on the earth in Israel 2000 years ago. The debate begins when the subject of Jesus’ full identity is discussed. Almost every major religion teaches that Jesus was a prophet or a good teacher or a godly man.
So, who did Jesus claim to be? Who does the Bible say He is? First, let’s look at Jesus’ words in John 10:30, “I and the Father are one.” John 1:1 says “the Word was God.” John 1:14 says “the Word became flesh.” This clearly indicates that Jesus is God in the flesh. Thomas the disciple declared to Jesus, “My Lord and my God” (John 20:28). Jesus does not correct him. The apostle Paul describes Him as, “…our great God and Savior, Jesus Christ” (Titus 2:13). The apostle Peter says the same, “…our God and Savior Jesus Christ” (2 Peter 1:1). God the Father is witness of Jesus’ full identity as well, “But about the Son he says, ‘Your throne, O God, will last forever and ever, and righteousness will be the scepter of your kingdom.’” Old Testament prophecies of Christ announce His deity, “For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace” (Isaiah 9:6).
Why is the question over Jesus’ true identity so important? Why does it matter whether or not Jesus is God? The most important reason that Jesus has to be God is that if He is not God, His death would not have been sufficient to pay the penalty for the sins of the whole world (1 John 2:2). Only God could pay such an infinite penalty (Romans 5:8; 2 Corinthians 5:21). Jesus had to be God so that He could pay our debt. Jesus had to be man so He could die. Salvation is available only through faith in Jesus Christ. Jesus’ deity is why He is the only way of salvation. Jesus’ deity is why He proclaimed, “I am the way and the truth and the life. No one comes to the Father except through me” (John 14:6).
