Romans 7:7
What are we then to conclude? Is the law sin? Of course not! Yet, if it had not been for the law, I should not have learned what sin was, for I should not have known what an evil desire was, if the law had not said, "You must not have an evil desire."
Romans 7:13
Did that which is good, then, result in death to me? Of course not! It was sin that did it, so that it might show itself as sin, for by means of that good thing it brought about my death, so that through the command sin might appear surpassingly sinful.
Romans 8:7
Because one's thinking the things suggested by the lower nature means enmity to God, for it does not subject itself to God's law, nor indeed can it.
