It was only after the resurrection that the disciples began to understand what Jesus had been telling them (
John 2:22). Even after the resurrection they did not understand about the second coming because they asked Him if now was the time that He would restore the kingdom to Israel (
Acts 1:6). Jesus told them that they should not be concerned about the timing of the coming kingdom, but they should take the gospel to the whole world (
Acts 1:8). Then He was taken up from them into heaven, and two angels came to them and said, “Men of Galilee, why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven” (
Acts 1:11). Here we finally have a clear indication that there will be a second coming after an undisclosed time period.
The Old Testament had several mysteries regarding the Messiah: would He be a divine figure or a human descendant of David? The New Testament gives the answer—both, because of the Incarnation. Would the Messiah be cut off or reign forever? The New Testament gives the answer—both, because of the Resurrection. Would the Messiah come to suffer or to reign? The New Testament once again gives the answer—both, because He would come twice.
