1 Corinthians 15

50 I declare to you, brothers, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 51Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: "Death has been swallowed up in victory."
55"Where, O death, is your victory?
Where, O death, is your sting?" 56The sting of death is sin, and the power of sin is the law. 57But thanks be to God! He gives us the victory through our Lord Jesus Christ.
