Romans 8:7-9

Living Bible

⁷ because the old sinful nature within us is against God. It never did obey God’s laws and it never will. ⁸ That’s why those who are still under the control of their old sinful selves, bent on following their old evil desires, can never please God.

⁹ But you are not like that. You are controlled by your new nature if you have the Spirit of God living in you. (And remember that if anyone doesn’t have the Spirit of Christ living in him, he is not a Christian at all.)
