1 Corinthians 15:51-53 NIV

[51] Listen, I tell you a mystery: We will not all sleep, but we will all be changed— [52] in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. [53] For the perishable must clothe itself with the imperishable, and the mortal with immortality.
