Romans 8:7-9

Names of God Bible

⁷ This is so because the corrupt nature has a hostile attitude toward God. It refuses to place itself under the authority of God’s standards because it can’t. ⁸ Those who are under the control of the corrupt nature can’t please God. ⁹ But if God’s Spirit lives in you, you are under the control of your spiritual nature, not your corrupt nature.

Whoever doesn’t have the Spirit of Christ doesn’t belong to him.
