Romans 6
17 Ref But thanks be to God, that, whereas ye were servants of sin, ye became obedient from the heart to that form of teaching whereunto ye were delivered;
18 Ref and being made free from sin, ye became servants of righteousness.
19 Ref I speak after the manner of men because of the infirmity of your flesh: for as ye presented your members `as' servants to uncleanness and to iniquity unto iniquity, even so now present your members `as' servants to righteousness unto sanctification.
