From Owen’s Of the Mortification of Sin in Believers
Sin will not only be striving, acting, rebelling, troubling, disquieting, but if let alone, if not continually mortified, it will bring forth great, cursed, scandalous, soul-destroying sins (52).
Sin aims always at the utmost; every time it rises up to tempt or entice, might it have its own course, it would go out to the utmost sin in that kind. Every unclean thought or glance would be adultery if it could; every covetous desire would be oppression, every thought of unbelief would be atheism, might it grow to its head (53).
Not to be daily mortifying sin is to sin against the goodness, kindness, wisdom, grace, and love of God, who has furnished us with a principle of doing it (54).
Let not that man think he makes any progress in holiness who walks not over the bellies of his lusts (55).
The root of an unmortified course is the digestion of sin without bitterness in the heart (56).
