(12-14) Practical and hortatory consequence. Therefore expel sin, and refuse to obey its evil promptings. Keep your bodies pure and clean. Let them no longer be weapons in the hands of wickedness; let them rather be weapons with which to fight the battle of righteousness and of God. You have every encouragement to do this. For sin shall no longer play the tyrant over you. The stern and gloomy Empire of Law (which only served to heighten the guilt of sin) is over, and in its stead the only power to which you are subject is that of free forgiveness.
