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.

I talk like regular people because of your body's weakness. Since you let your body do bad things, now let it do good things for holiness.
