In a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.--1 Corinthians 15:52
When Christ the great Lifegiver shall come in the clouds of heaven, to raise the dead, there will be a terrible earthquake. The trump of God will be heard resounding through earth's remotest bounds, and the voice of Jesus will call forth the dead from their graves to immortal life.
You have not seen Christ coming with power and great glory which shall illuminate the earth from the east to the west, from north to south, like the lightning's flash. (Letter 2, August 24, 1874)
The living righteous are changed "in the moment, in the twinkling of an eye." At the voice of God they were glorified; now they are made immortal and with the risen saints are caught up to meet their Lord in the air. Angels "gather together His elect from the four winds, from one end of heaven to the other." Little children are borne by holy angels to their mothers' arms. Friends long separated by death are united, nevermore to part, and with songs of gladness ascend together to the City of God.
On each side of the cloudy chariot are wings, and beneath it are living wheels; and as the chariot rolls upward, the wheels cry, "Holy," and the wings, as they move, cry, "Holy," and the retinue of angels cry, "Holy, holy, holy, Lord God Almighty." And the redeemed shout, "Alleluia!" as the chariot moves on-ward toward the New Jerusalem. (The Great Controversy, 645)
Before the glory of Him who is to reign, the mountains will tremble and bow, the rocks will be moved out of their place; for once more will the Lord shake not alone the earth, but the heavens also. The scattered ones who have fled for their lives to the rocks, the dens, the caverns of the earth, because of the fury of the oppressor, will be made glad at the voice of God. (Manuscript 56, May 21, 1886)
REFLECTION: What a scene will these mountains and hills [in Switzerland] present when Christ, the Lifegiver, shall call forth the dead! They will come from caverns, from dungeons, from deep wells, where their bodies have been buried. They will come forth with the sound of the trumpet and the voice of God at that last great and terrible day of the Lord. (Letter 97, April 29, 1886)
