Jesus must reign until he has put all his enemies under his feet

1 Corinthians 15:

...

¹²But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead? ¹³If there is no resurrection of the dead, then not even Christ has been raised. ¹⁴And if Christ has not been raised, our preaching is useless and so is your faith. ¹⁵More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. ¹⁶For if the dead are not raised, then Christ has not been raised either. ¹⁷And if Christ has not been raised, your faith is futile; you are still in your sins. ¹⁸Then those also who have fallen asleep in Christ are lost. ¹⁹If only for this life we have hope in Christ, we are to be pitied more than all men.

²⁰But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. ²¹For since death came through a man, the resurrection of the dead comes also through a man. ²²For as in Adam all die, so in Christ all will be made alive. ²³But each in his own turn: Christ, the firstfruits; then, when he comes, those who belong to him. ²⁴Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power. ²⁵For he must reign until he has put all his enemies under his feet. ²⁶The last enemy to be destroyed is death. ²⁷For he "has put everything under his feet."^c]">[c] Now when it says that "everything" has been put under him, it is clear that this does not include God himself, who put everything under Christ. ²⁸When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.

²⁹Now if there is no resurrection, what will those do who are baptized for the dead? If the dead are not raised at all, why are people baptized for them? ³⁰And as for us, why do we endanger ourselves every hour? ³¹I die every day—I mean that, brothers—just as surely as I glory over you in Christ Jesus our Lord. ³²If I fought wild beasts in Ephesus for merely human reasons, what have I gained? If the dead are not raised,
"Let us eat and drink, for tomorrow we die."^d]">[d] ³³Do not be misled: "Bad company corrupts good character." ³⁴Come back to your senses as you ought, and stop sinning; for there are some who are ignorant of God—I say this to your shame.
