19 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, to ([work]) iniquity; even so now yield your members servants to righteousness, to ([work]) holiness.
19
I am using an example from everyday life because of your human limitations. Just as you used to offer yourselves as slaves to impurity and to ever-increasing wickedness, so now offer yourselves as slaves to righteousness leading to holiness.
