1 Corinthians 15:25-28
15:25 For he must reign until he has put all his enemies under his feet.
15:26 The last enemy to be eliminated is death.
15:27 For he has put everything in subjection under his feet. But when it says “everything” has been put in subjection, it is clear that this does not include the one who put everything in subjection to him.
15:28 And when all things are subjected to him, then the Son himself will be subjected to the one who subjected everything to him, so that God may be all in all.
