And when he had spoken these things Had given them these instructions; while they beheld And had their eyes fixed upon him, with great earnestness and high expectation of some extraordinary event, consequent on this solemn preparation, and while they were receiving his blessing, (Luke 24:51,) he was taken up Was lifted up from the ground, in a miraculous manner, gradually rising higher and higher, till at length a cloud Conducted probably by the ministry of angels; received him out of their sight That is, covered him about, and carried him into heaven; not in a sudden, but leisurely manner, that they might behold him departing, and see the proof of his having come down from heaven. He did not grant his disciples the privilege of seeing him come out of the grave, because they might see him after he was risen, which would be a satisfaction sufficient; but as they could not see him in heaven while they continued on earth, he granted them the favour of seeing him go up toward heaven, and of having their eyes fixed upon him with so much care and intention of mind, that they could not be deceived. Observe, reader, our Lord ascended into heaven from the mount of Olives, at or near the place where he had been apprehended and bound, and from whence he had been led away like a felon to be tried for his life, insulted, scourged, and condemned to crucifixion! He now goes off in triumph from the same mountain, into a place and state worthy of his innocence and dignity. And while they looked steadfastly toward heaven That is, continued with their eyes fixed the way that he was gone; as he went up In his triumphant ascent; behold two men Two angels in the form of men; stood by them Unexpectedly. Though they had assumed the form and garb of men, they were, by the majesty and splendour of their appearance, known of the apostles to be angels. And, indeed, as his resurrection had been honoured with the appearance of angels, it was natural to think that his ascension into heaven would be so likewise; in white apparel Emblematical of their holiness and happiness; which also said, Ye men of Galilee So they call them, to put them in mind of the meanness of their original condition: Christ had put a great honour upon them, in making them his ambassadors; but they must remember they are men of Galilee, illiterate and despised by the wise and learned of the world. Why stand ye here, gazing up into heaven With so much surprise and amazement? it seems, they looked up steadfastly after he was gone out of sight, expecting, perhaps, to see him come down again immediately. This same Jesus, which is taken up into heaven Who is gone to that world from whence he came, and in which he is to make his final abode; shall so come as you have seen him go into heaven He shall come in like manner, that is, visible, in a cloud, in his own person, with the same body, and with such majesty and glory as you have now seen him ascend with. “The angels spake of his coming to judge the world at the last day, a description of which Jesus had given in his lifetime, saying, (Matthew 16:27,) The Son of man shall come in the glory of his Father, &c. We may therefore infer that the cloud whereon he now ascended, being like that in which he is to come again, was more bright and pure than the clearest lambent flame; for it was the glory of the Father, that is, the shechinah, or visible symbol of the divine presence, which appeared to the patriarchs in ancient times; which filled the temple at its dedication, (2 Chronicles 7:3,) and which, in its greatest splendour, cannot be beheld with mortal eyes, and so, for that reason, is called the light inaccessible, in which God dwells, 1 Timothy 6:16. It was on this occasion, probably, that our Lord's body was changed, acquiring the glories of immortality, perhaps, in the view of his disciples; for flesh and blood, such as he rose with, cannot inherit the kingdom of God. Accordingly, the body which he now has is called a glorious body, and declared to be of the same nature with that which the saints shall have after their resurrection, Philippians 3:21. Wherefore, though the Scripture is silent as to the time when this change passed upon Christ's body, we must suppose that it happened either immediately before his ascension, or in the time of it, or soon after it. As he ascended up into the skies, the flaming cloud which surrounded him, leaving a tract of light behind it, marked his passage through the air, but gradually lost its magnitude in the eyes of them who stood below, till, soaring high, he and it vanished out of their sight.
“In this illustrious manner did the Saviour depart, after having finished the grand work which he came down upon earth to execute; a work which God himself, in the remotest eternity, contemplated with pleasure; which angels anciently with joy described as to happen; and which, through all eternity to come, shall, at periods the most immensely distant from the time of its execution, be looked back upon with inexpressible delight by every inhabitant of heaven. For though the little affairs of time may vanish altogether and be lost, when they are removed far back by the endless progression of duration, this object is such, that no distance, however great, can lessen it. The kingdom of God is erected upon the incarnation and sufferings of the Son of God, the kingdom and city of God comprehending all the virtuous beings that are in the universe, made happy by goodness and love; and therefore none of them can ever forget the foundation on which their happiness stands firmly established. In particular, the human species, recovered by this labour of the Son of God, will view their deliverer, and look back on his stupendous undertaking with high ravishment, while they are feasting without interruption on its sweet fruits, ever growing more delicious. The rest of the members likewise of the city of God will contemplate it with perpetual pleasure, as the happy means of recovering their kindred that were lost; and, it may be, as the grand confirmation of the whole rational system, in their subjection to him who liveth and reigneth for ever, and whose favour is better than life.” Macknight.
