1 Corinthians 15:24-27

Then the final stage of completion comes, when he will bring to an end every other rulership, authority, and power, and he will hand over his kingdom to Father God. Until then he is destined to reign as King until all hostility has been subdued and placed under his feet. And the last enemy to be subdued and eliminated is death itself. The Father has placed all things in subjection under the feet of Christ. Yet when it says, “all things,” it is understood that the Father does not include himself, for he is the one who placed all things in subjection to Christ.
