Get a Clear and Abiding Sense Upon Your Mind and
Conscience of the Guilt, Danger, and Evil of Your Sin
Part 3 of 10 of “On the Mortification of Sin in Believers”
“Take heed,” says the author of Hebrews (3:12); use all means, consider your temptations, watch diligently; there is a treachery, a deceit in sin, that attempts to harden your heart so that you no longer fear God. Every indulged sin will make at least some progress toward this goal. You that were once tender, and used to melt under the Word, under convictions, will grow to become “sermon-proof” and “conviction-proof.” You that did tremble at the presence of God, at thoughts of eternal death, and at the time of your appearance before Him, will grow to have a hardness of your spirit so that you are no longer moved by these things. Your soul and your sin shall be spoken of and spoken to, and you shall not be at all concerned, but shall be able to skip over the disciplines of praying, meditating, studying the Scriptures, and your heart will not be in the least affected. Sin will become a trivial thing to you; you will pass it by as a light thing—this is what sin is aiming at.
And what will be the end of such a condition? Can a sadder thing befall you? Is it not enough to make any heart tremble to think of being brought into a condition were it has carefree, untroubled thoughts about sin? Also, trivial thoughts about grace, mercy, of the blood of Christ, of the law, of heaven, and hell all accompany trivial thoughts about sin. Take heed, this is that which your sin is working toward—the hardening of the heart, searing of the conscience, blinding of the mind, stupefying of the heart’s affections, and deceiving of the whole soul.
