1 Corinthians 15:50-52

Now I say this, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, and what decays cannot inherit what does not decay. Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed— in a moment, in the twinkling of an eye, at the last shofar. For the shofar will sound, and the dead will be raised incorruptible, and we will be changed.
