1 Corinthians 15:1-6; 1 Corinthians 15:54-58
Now, brothers, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand.
By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,
that he was buried, that he was raised on the third day according to the Scriptures,
and that he appeared to Peter, and then to the Twelve.
After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.
When 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."
"Where, O death, is your victory? Where, O death, is your sting?"
The sting of death is sin, and the power of sin is the law.
But thanks be to God! He gives us the victory through our Lord Jesus Christ.
Therefore, 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.
