12 Therefore, let not sin reign in your mortal body, such that you would obey its desires.
13 Nor should you offer the parts of your body as instruments of iniquity for sin. Instead, offer yourselves to God, as if you were living after death, and offer the parts of your body as instruments of justice for God.
14 For sin should not have dominion over you. For you are not under the law, but under grace.
15 What is next? Should we sin because we are not under the law, but under grace? Let it not be so!
16 Do you not know to whom you are offering yourselves as servants under obedience? You are the servants of whomever you obey: whether of sin, unto death, or of obedience, unto justice.
17 But thanks be to God that, though you used to be the servants of sin, now you have been obedient from the heart to the very form of the doctrine into which you have been received.
18 And having been freed from sin, we have become servants of justice.
