If you read what I’ve written here today, it will deepen your hatred for sin and spark your love for holiness. At least, I think it will. All I’ve done is summarize chapter two of John Owen’s classic Overcoming Sin and Temptation, a book that has been precious to generations of Christians as they have battled sin and pursued holiness. Read on!
Here is Owen’s thesis for the chapter: “The choicest believers, who are assuredly freed from the condemning power of sin, ought yet to make it their business all their days to mortify [“kill” or “put to death”] the indwelling power of sin.” In other words, Christians battle sin and put it to death. They battle sin every day until the day they die. They never stop. They never let up.
And so Owen asks you:
“Do you mortify?
Do you make it your daily work?
Be always at it while you live.
Cease not a day from this work.
Be killing sin or it will be killing you.”
And then he gives 6 reasons you must keep putting sin to death.
1. Indwelling Sin Always Lives On
Until the day you die or the day the Lord returns, you will always have sin within you. “We have a ‘body of death’ (Rom. 7:24), from whence we are not delivered but by the death of our bodies (Phil. 3:20). Now, it being our duty to mortify, to be killing of sin while it is in us, we must be at work. He that is appointed to kill an enemy, if he leave striking before the other ceases living, does but half his work.”
2. Indwelling Sin Continues to Act
This indwelling sin continues to act upon you and against you through your entire life. “Sin does not only still abide in us, but is still acting, still laboring to bring forth the deeds of the flesh. When sin lets us alone we may let sin alone; but as sin is never less quiet than when it seems to be most quiet, and its waters are for the most part deep when they are still, so ought our contrivances against it to be vigorous at all times and in all conditions, even where there is least suspicion.”
“Sin is always acting, always conceiving, always seducing and tempting. Who can say that he had ever anything to do with God or for God, that indwelling sin had not had a hand in the corrupting of what he did?”
“There is not a day but sin foils or is foiled, prevails or is prevailed on.”
3. Indwelling Sin Produces Soul-Destroying Sin
This remaining, indwelling sin is no trifling matter, but will continue to try to utterly destroy you all throughout your life. “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.” And then, perhaps the most important thing I’ve ever learned from Owen: “Sin always aims for 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 of 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.”
