1 Corinthians 15:24-28

and then the end will come. At that time Christ will destroy all rulers, authorities, and powers, and he will hand over the kingdom to God the Father. Christ must rule until he puts all enemies under his control. The last enemy to be destroyed will be death. The Scripture says that God put all things under his control. When it says “all things” are under him, it is clear this does not include God himself. God is the One who put everything under his control. After everything has been put under the Son, then he will put himself under God, who had put all things under him. Then God will be the complete ruler over everything.
