Romans 7:7
Then what shall we conclude? That the Law is sin? Certainly not! Yet, if it had not been for the Law, I should never have learned what sin was; I should not have known what it was to covet if the Law had not said, "You must not covet."
Romans 7:13
Did what was good, then, prove the death of me? Certainly not! It was sin that did so, so that it might be recognized as sin, because even through something that was good it effected my death, so that through the command it might appear how immeasurably sinful sin was.
Romans 8:7
For to be physically minded means hostility to God, for it refuses to obey God's law, indeed it cannot obey it.
