1 Corinthians 15:20-23, 52-53

But the truth is, Christ is risen from the dead, as the firstfruit of a great resurrection harvest of those who have died. For since death came through a man, Adam, it is fitting that the resurrection of the dead has also come through a man, Christ. Even as all who are in Adam die, so also all who are in Christ will be made alive. But each one in his proper order: Christ, the firstfruits, then those who belong to Christ in his presence.

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.
