The Mortification of Sin in Believers

“He (The Holy Spirit) alone clearly and fully convinces the heart of the evil and guilt and danger of the corruption, lust, or sin to be mortified. Without this conviction, or whilst it is so faint that the heart can wrestle with it or digest it, there will be no thorough work made. An unbelieving heart (as in part we have all such) will shift with any consideration, until it be overpowered by clear and evident convictions. Now this is the proper work of the Spirit: "He convinces of sin," John 16:8; he alone can do it. If men's rational considerations, with the preaching of the letter, were able to convince them of sin, we should, it may be, see more convictions than we do. There comes by the preaching of the word an apprehension upon the understandings of men that they are sinners, that such and such things are sins, that themselves are guilty of them; but this light is not powerful, nor does it lay hold on the practical principles of the soul, so as to conform the mind and will unto them, to produce effects suitable to such an apprehension. And therefore it is that wise and knowing men, destitute of the Spirit, do not think those things to be sins at all wherein the chief movings and actings of lust do consist. It is the Spirit alone that can do, that does, this work to the purpose. And this is the first thing that the Spirit does in order to the mortification of any lust whatever, -- it convinces the soul of all the evil of it, cuts off all its pleas, discovers all its deceits, stops all its evasions, answers its pretences, makes the soul own its abomination, and lie down under the sense of it. Unless this be done all that follows is in vain.” – John Owens (1616-1683)

And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: Of sin, because they believe not on me…John 16:8-9
