Romans 7:7

7:7 What shall we say then? Is the law sin? Absolutely not! Certainly, I would not have known sin except through the law. For indeed I would not have known what it means to desire something belonging to someone else if the law had not said, “Do not covet.”

Romans 8:9

8:9 You, however, are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you. Now if anyone does not have the Spirit of Christ, this person does not belong to him.
