1 Corinthians 15:51-53 New Revised Standard Version (NRSV)
51 Listen, I will tell you a mystery! We will not all die,[a] but we will all be changed, 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 imperishable, and we will be changed. 53 For this perishable body must put on imperishability, and this mortal body must put on immortality.
