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.
Those who live righteously are not in bondage. Those who practice sin are slaves of sin, but those who the Son sets free, are truly free. Before our conversion, we have surrendered our lives as slaves of all kinds of uncleanness and to one kind of wickedness after another. Now we should dedicate those same lives as slaves of righteousness, so that we would be truly holy.
