Let not sin therefore reign in your mortal body, that you should obey it in its lusts.
All Commentaries on Romans 6:12 Go To Romans 6
Augustine of Hippo
AD 430
We must engage in a constant, daily struggle not to obey those desires which are forbidden or improper. For from this sort of fault it comes about that the eye is turned to where it ought not to look, and if this fault grows strong and prevails, even bodily adultery is carried out, which is committed in the heart as much more quickly as thought is quicker than action and has nothing to hinder or delay it.
