1 Corinthians 15:51-53

Behold, I tell you a mystery: We shall not all fall asleep, but we shall all be changed, in an instant, in the twinkling of an eye, at the last trumpet; for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must needs put on incorruptibility, and this mortal put on immortality.
