Romans 6:16-18

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.
