Romans 6:18-19

Romans 6:18-19. Being then made free from sin, ye became the servants of righteousness. 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.

How powerfully this plea ought to tell with any whose former life was full of positive, plain uncleanness in the sight of God! And how earnestly should the redeemed spirit cry to God to preserve the body pure and chaste before him!
