1 Corinthians 15:51-53

15:51 Listen, I will tell you a mystery: We will not all sleep, but we will all be changed – 15:52 in a moment, in the blinking of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. 15:53 For this perishable body must put on the imperishable, and this mortal body must put on immortality.
