Romans 6:16-20

16Do you not know that to whatever you yield yourselves as slaves for obedience, you are slaves to what you obey—whether to sin resulting in death, or to obedience resulting in righteousness?

17But thanks be to God that though you were slaves of sin, you wholeheartedly obeyed the form of teaching under which you were placed;

18and after you were set free from sin, you became enslaved to righteousness.

19I speak in human terms because of the weakness of your flesh. For just as you yielded your body parts as slaves to uncleanness and lawlessness, leading to more lawlessness, so now yield your body parts as slaves to righteousness, resulting in holiness.

20For when you were slaves of sin, you were free with regard to righteousness.
