1 Corinthians 15:51-53

Listen, and I will tell you a divine mystery: not all of us will die, but we will all be transformed. It will happen in an instant —in the twinkling of his eye. For when the last trumpet is sounded, the dead will come back to life. We will be indestructible and we will be transformed. For we will discard our mortal “clothes” and slip into a body that is imperishable. What is mortal now will be exchanged for immortality.
