Not all religious groups identifying themselves as Christians agree that Jesus is God. Mormons, Jehovah’s Witnesses, and many other such groups espouse different beliefs about who and what Jesus is. Islam, though not a Christian religion, recognizes Jesus as a great prophet but denies that he is divine. All of these religions challenge the traditional Christian view of Jesus Christ as God incarnate. In addition, skeptics consider the belief that Jesus was God to be myth.
Christians have nothing to fear from these challenges to what we believe about Christ. If Jesus is God as Christianity historically has taught, then we should find that the evidence supports this belief. On the other hand, if the evidence were to show that Jesus was not God, we would certainly want to know it.
