It came to pass, while He blessed them, He was parted from them, and carried up into heaven. And they worshipped Him, and returned to Jerusalem with great joy. Luke 24:51, 52. RRe 300.1
Christ had ascended to heaven in the form of humanity. The disciples had beheld the cloud receive Him. The same Jesus who had walked and talked and prayed with them; who had broken bread with them; who had been with them in their boats on the lake; and who had that very day toiled with them up the ascent of Olivet,—the same Jesus had now gone to share His Father’s throne. And the angels had assured them that the very One whom they had seen go up into heaven, would come again even as He had ascended.... RRe 300.2
When the disciples went back to Jerusalem, the people looked upon them with amazement. After the trial and crucifixion of Christ, it had been thought that they would appear downcast and ashamed. Their enemies expected to see upon their faces an expression of sorrow and defeat. Instead of this there was only gladness and triumph. Their faces were aglow with a happiness not born of earth. They did not mourn over disappointed hopes, but were full of praise and thanksgiving to God. With rejoicing they told the wonderful story of Christ’s resurrection and His ascension to heaven, and their testimony was received by many.—The Desire of Ages, 832. RRe 300.3
