Romans 6:17-19

ASV(i) 17 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 and being made free from sin, ye became servants of righteousness. 19 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.
