Rom 6:14 For sin shall not [any longer] exert dominion over you, since now you are not under Law [as slaves], but under grace [as subjects of God's favor and mercy]. Rom 6:17 But thank God, though you were once slaves of sin, you have become obedient with all your heart to the standard of teaching in which you were instructed and to which you were committed.
Rom 6:18 And having been set free from sin, you have become the servants of righteousness (of conformity to the divine will in thought, purpose, and action).
