Sin aims always at the utmost; every time it rises up to tempt or entice, if it has its own way it will go out to the utmost sin in that kind. Every unclean thought or glance would be adultery if it could, every thought of unbelief would be atheism if allowed to develop. Every rise of lust, if it has its way reaches the height of villainy; it is like the grave that is never satisfied. The deceitfulness of sin is seen in that it is modest in its first proposals but when it prevails it hardens menโs hearts, and brings them to ruin.
John OwenLet no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.
John OwenA true saving knowledge of sin is to be had only in the Lord Christ: in him may we see the desert of our iniquities.
