1 Corinthians 15:20-23, 52-53

But now hath Christ been raised from the dead, the firstfruits of them that are asleep. For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive. But each in his own order: Christ the firstfruits; then they that are Christ’s, at his coming.

in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality.
