According to the New Testament
It was the author of Luke and Acts who developed the notion of Jesus being physically taken up into heaven. Mark, in its original form, implies that the resurrection and the ascension of Jesus into heaven were one and the same event. Otherwise, the gospels have nothing to say on this. In Luke 24:51, Jesus ascended into heaven on the evening of the day of his resurrection. Acts of the Apostles, written some time later, at verses 1:3,9, says that the risen Jesus stayed on earth for forty days and was then taken up bodily into heaven. The answer to this question depends on which gospel account is used: The first gospel to be written, Mark's Gospel, originally ended at verse 16:8, when the women fled from the sepulchre in terror, telling no one. The 'Long Ending', added much later, is somewhat similar to the account in Luke's Gospel, Mark 16:14 saying that Jesus appeared to the eleven at a meal, then they dispersed and preached everywhere. Thus: In the original Gospel, Jesus was never seen after his resurrection. .In the Long Ending, Jesus only appeared to the disciples at a meal, he was taken up into heaven, then they dispersed and began to preach. Matthew's Gospel says that Jesus appeared briefly to the disciples at a mountain in Galilee and told them to spread out and preach. Jesus said he would be with the disciples always, but the gospel is silent on what happened to Jesus in his physical body.
