Now when He had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight. 10 And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, 11 who also said, “Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.”
“It is appointed man once to die and then the judgement” Heb. 9:27.
While man is in the body he does not see such things as are in heaven, unless the sight of his spirit is opened; when this is opened, then he sees. In this way John saw the things described in Revelation; and in like manner the prophets saw; and they were therefore called Seers, and were said to have their eyes opened. In this way also angels were seen in ancient times, and the Lord also was thus seen by the disciples after His resurrection. This sight is the sight of the spiritual man; and because in this state all things appear representatively, John was in it. He who knows nothing about this sight, believes that angels, when seen by men, have taken on a human form, and that when they vanished from their sight they laid it aside; but this is not so; angels then appeared in their own form, which is the human form, not before the sight of men’s bodily eyes, but before the sight of their spirit, which sight was then opened. This is evident from the Lord’s being seen by the disciples [after His resurrection], when He Himself showed to them that He was a man in a complete human form (Luke 24:39; John 20:20-28); and yet He became invisible. When they saw Him the eyes of their spirit were opened, but when He became invisible those eyes were closed. That man has such a sight is clear to me from much experience, for all things I have seen in the heavens have been seen by that sight. At such times I was in the same state of wakefulness as when they were not seen. But at the present time that sight is seldom opened to anyone by the Lord, and for many reasons.
