1 Corinthians 15:1-4, 1 Corinthians 15:53-58.

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.

1 Corinthians 15:1-4 NIV

For this perishable body must put on the imperishable, and this mortal
body must put on immortality. When the perishable puts on the
imperishable, and the mortal puts on immortality, then shall come to
pass the saying that is written:
"Death is swallowed up in victory." "O death, where is your victory?
O death, where is your sting?" The sting of death is sin, and the
power of sin is the law. But thanks be to God, who gives us the
victory through our Lord Jesus Christ. Therefore, my beloved brothers,
be steadfast, immovable, always abounding in the work of the Lord,
knowing that in the Lord your labor is not in vain.

1 Corinthians 15:53-58 ESV

God bless you.
