I'll give you the true answer, which many Christians will hate and reject. But it's the truth, so I will go to the trouble of providing it. Jesus didn't know he was the Son of God. When his followers started calling his this, he eventually began to believe it himself. Finally, he became convinced of it. He decided that he would fulfill the prophecy of the Messiah, by deliberately getting himself sacrificed on the Passover. He would thus become the Lamb of God. Jesus drew Judas aside and told Judas to go to the priests and betray his location. Judas loved Jesus and didn't want to do this, but Jesus insisted. Judas did it. Jesus was taken, as Jesus intended should happen. Jesus was tortured. When Judas saw this, he was horrified, because Jesus had assured him that he, Jesus, would be unharmed -- that God would protect him. Hence, Judas, the most loyal of all the Disciples, killed himself out of remorse. Jesus was hung on the cross to die. He had not expected this to happen. It suprised and saddened him. This prompted him to utter the words in his native language, "Why hast thou forsaken me?" He said this because, at this point in his life, he had accepted the belief that he was the Son of God, the true Messiah, and he believed that his Father in heaven would never allow him to be tortured and executed. Only when he was on the cross did he realize that he was going to die, and God was not going to save him from death. The later bits of the story, about his resurrection and his talks with the Disciples are, of course, pure fantasy. When you're dead, you're dead. The reason the body of Jesus disappeared from the tomb is because his followers took it out and hid it somewhere. This is obvious, to a rational person. I could tell you what they did with the body, but I think I'll stop here. You've had enough truth, and I'm pretty sure most of you can't handle it.
