BLB(i)
17 But thanks be to God that you who were slaves of sin have now become obedient from the heart to the pattern of teaching to which you were committed.
18 And having been set free from sin, you have become slaves to righteousness.
19 I speak in human terms on account of the weakness of your flesh. For just as you yielded your members in bondage to impurity and to lawlessness unto lawlessness, so now yield your members in bondage to righteousness unto sanctification.
