1 Corinthians 15:20

¹⁸ Then they also which are fallen asleep in Christ are perished.

¹⁹ If in this life only we have hope in Christ, we are of all men most miserable.

But now is Christ risen from the dead, and become the firstfruits of them that slept.

²¹ For since by man came death, by man came also the resurrection of the dead.

²² For as in Adam all die, even so in Christ shall all be made alive.

Do read the surrounding verses too, because the context often says more than a single verse.
