Romans 6:19-20

Romans 6:19-20. I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness. For when ye were the servant of sin, ye were free from righteousness.

You disdained the silken bonds of piety, you said that you would never wear what you called the iron fetters of grace; you were "Free from righteousness." So, surely, now that you are the servants of righteousness, you should seek to be free from sin.
