I Corinthians 15:51-58
15:51 Listen, I will tell you a mystery! We will not all die, but we will all be changed,

15:52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed.

15:53 For this perishable body must put on imperishability, and this mortal body must put on immortality.

15:54 When this perishable body puts on imperishability, and this mortal body puts on immortality, then the saying that is written will be fulfilled: "Death has been swallowed up in victory."

15:55 "Where, O death, is your victory? Where, O death, is your sting?"

15:56 The sting of death is sin, and the power of sin is the law.

15:57 But thanks be to God, who gives us the victory through our Lord Jesus Christ.

15:58 Therefore, my beloved, be steadfast, immovable, always excelling in the work of the Lord, because you know that in the Lord your labor is not in vain.
