..."And if Christ has not been raised, your faith is futile; you are still in your sins. Then those also who have fallen asleep in Christ are lost. If only for this life we have hope in Christ, we are to be pitied more than all men. BUT Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep...
...When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written is true: 'Death has been swallowed up in victory.'
...The sting of death is sin, and the power of sin is the law. But thanks be to God! He gave us the victory through our Lord Jesus Christ."
1Cor 15:16-20, 54, 56-67 (emphasis added)
