1 Corinthians 15:21 Meaning

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

20But now is Christ risen from the dead, and become the firstfruits of them that slept.

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

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

23But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
