12 Let not sin therefore rule as king in your mortal (short-lived, perishable) bodies, to make you yield to its cravings and be subject to its lusts and evil passions.
13 Do not continue offering or yielding your bodily members [and faculties] to sin as instruments (tools) of wickedness. But offer and yield yourselves to God as though you have been raised from the dead to [perpetual] life, and your bodily members [and faculties] to God, presenting them as implements of righteousness.
14 For sin shall not [any longer] exert dominion over you, since now you are not under Law [as slaves], but under grace [as subjects of God's favor and mercy].
15 What then [are we to conclude]? Shall we sin because we live not under Law but under God's favor and mercy? Certainly not!
16 Do you not know that if you continually surrender yourselves to anyone to do his will, you are the slaves of him whom you obey, whether that be to sin, which leads to death, or to obedience which leads to righteousness (right doing and right standing with God)?
17 But thank God, though you were once slaves of sin, you have become obedient with all your heart to the standard of teaching in which you were instructed and to which you were committed.
18 And having been set free from sin, you have become the servants of righteousness (of conformity to the divine will in thought, purpose, and action).
