1 Corinthians 15 (New International Version) : 20-25 & 54-58

20But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. 21For since death came through a man, the resurrection of the dead comes also through a man. 22For as in Adam all die, so in Christ all will be made alive. 23But each in his own turn: Christ, the firstfruits; then, when he comes, those who belong to him. 24Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power. 25For he must reign until he has put all his enemies under his feet. 26The last enemy to be destroyed is death.

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.”[g]
55“Where, O death, is your victory?
Where, O death, is your sting?”[h] 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.

58Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
