Romans 7:7-8

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.” 7:8 But sin, seizing the opportunity through the commandment, produced in me all kinds of wrong desires. For apart from the law, sin is dead.

Romans 7:14

7:14 For we know that the law is spiritual – but I am unspiritual, sold into slavery to sin.
