1 Corinthians 15:51–53
15:51 Behold, I tell you a mystery. We will not all sleep, but we will all be changed,
15:52 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 will be changed.
15:53 For this perishable body must become imperishable, and this mortal must put on immortality.
