Jesus Christ Is Going To Actually Return
And when He had said this, as they were looking on, He was lifted up, and a cloud took Him out of their sight. And while they were gazing into heaven as He went, behold, two men stood by them in white robes, and said, "Men of Galilee, why do you stand looking into heaven? This Jesus, Who was taken up from you into heaven, will come in the same way as you saw Him go into heaven." Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem." (Acts 1:6-12 RSV)
