BLB(i)
51 Behold, I tell to you a mystery: We will not all sleep, but we will all be changed—
52 in an instant, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed.
53 For it behooves this, the perishable to put on the imperishable; and this, the mortal to put on immortality.
