The third miracle from the gospels that identified Jesus as God to the Jews was the Transfiguration of Jesus which appeared in all three of the Synoptic gospels. This account took place on a high mountain in the presence of Peter, James and John. The appearance of Jesus changed to show him in his heavenly glory. Appearing with Jesus was Moses and Elijah who represented the Law and the Prophets. In the Old Testament God (Yahweh) had appeared to both men by their request and spoke to them. God did not allow either one of them to see his face. Elijah is still alive in heaven but Moses was long since dead when he met with Jesus in the spirit. Jesus was conversing with them so it was obvious they knew each other already. It would be obvious to any Jew that God was now honoring their request to see his face, his human face.
To any Jew Jesus was saying I am the God who in times past spoke with my servants Moses and Elijah. This amazing miracle is contained in all four gospels and declares to all that Jesus is God come to earth in the flesh.
You must understand the times in which Jesus lived. A person couldn’t claim to be God without being stoned to death for blasphemy. Instead, Jesus taught in parables, spoke in riddles and often referred to Old Testament Scriptures in his sermons. The goal of Jesus was to fulfill Bible prophecies concerning the Messiah and let the people make up their own mind who he was. The fact the Synoptic gospels do not declare Jesus is God perfectly reflects first century Jewish culture and actually corroborates their authenticity in my mind.
Jesus came into this world with a ministry that was choreographed for three and a half years from his baptism to his crucifixion. Jesus had to reveal his identity as God slowly so as to have time to fulfill prophecy and teach about the kingdom of God. Notice in each of the gospels Jesus performed some miracles and then told the recipient not to tell anyone. This was because the time to reveal himself as God had not yet come. It was only toward the end of his ministry that Jesus openly admitted to the Jewish leaders and the Romans that he was God. Predictably, Jesus was sentenced to die for the blasphemy of claiming to be God. Jesus came so that he could die on the cross for our sins and that is why with his last breath Jesus said “It is finished”.
