1 Cor 15:51-52
51 But let me tell you something wonderful, a mystery I'll probably never fully understand. We're not all going to die — but we are all going to be changed. 52 You hear a blast to end all blasts from a trumpet, and in the time that you look up and blink your eyes — it's over. On signal from that trumpet from heaven, the dead will be up and out of their graves, beyond the reach of death, never to die again. At the same moment and in the same way, we'll all be changed.
