Most Christians didn't realize the reasons Jesus came back from the grave; nor did they realize that if he didn't stay around to teach his followers the importance of his dying on the cross, the spreading of the gospel wouldn't have the effect to stay alive. Jesus is the Son of God, who came down from heaven, in the flesh, as a baby, grew up as a man with no guile found in him. He went on to be crucified for the sins of man, and is become the Savior of the world, our mediator, and is now sitting on the right hand of God.
