The Deceitfulness of the Heart
Jeremiah 17:9
The heart is deceitful above all things, and desperately wicked: who can know it?


It appears —

I. FROM MEN'S GENERAL IGNORANCE OF THEIR OWN CHARACTER. They think, and reason, and judge quite differently in anything relating to themselves,' from what they do in those cases in which they have no personal interest. Accordingly, we often hear people exposing follies for which they themselves are remarkable, and talking with great severity against particular vices, of which, if all the world be not mistaken, they themselves are notoriously guilty. In vain do you tender to them instruction or reproof, for they turn away everything from themselves, and never once imagine that they are the persons for whose benefit these counsels and admonitions are chiefly intended. If we trace this self-ignorance to its source, we shall find that it is in general owing, not only to that partiality and fondness which we all have for ourselves, but to the prevalence of some particular passion or interest, which perverts the judgment in every case where that particular passion or interest is concerned. And hence it happens that some men can reason and judge fairly enough, even in cases in which they themselves are interested, provided it does not strike against their favourite passion or pursuit. Thus the covetous man will easily enough perceive the evil of intemperance, and perhaps condemn himself if he has been guilty of this sin in a particular instance. But he is altogether insensible to the dominion of his predominant passion, the love of money. It has become habitual to him. His mind is accustomed to it, so that in every case, where his interest is concerned, his judgment is warped, and in these instances he plainly discovers that he is totally unacquainted with his own character. The same observation applies to other particular vices.

II. FROM MEN'S GENERAL DISPOSITION ON ALL OCCASIONS TO JUSTIFY THEIR OWN CONDUCT. If we cannot justify the action itself, we attempt to extenuate its guilt from the peculiar circumstances of the case. We were placed in such and such a particular situation, which we could not avoid; our temptations were strong: we did not go the lengths that many others would have gone in similar circumstances; and the general propriety of our conduct is more than sufficient to overbalance any little irregularities with which we may sometimes be chargeable. Men even learn to call their favourite vices by softer names. Intemperance is only the desire of good fellowship; lewdness is gallantry, or the love of pleasure; pride, a just sense of our own dignity; and covetousness, or the love of money, a prudent regard to our worldly interest. Besides these single determinate acts of wickedness, of which we have now been speaking, there are numberless cases in which the wickedness cannot be exactly defined, but consists in a certain general temper and course of action, or in the habitual neglect of some duty, whose bounds are not precisely fixed. This is the peculiar province of self-deceit, and here, most of all, men are apt to justify their conduct, however plainly and palpably wrong. To give an example: There is not a word in our language that expresses more detestable wickedness than oppression. Yet the nature of this vice cannot be so exactly stated, nor the bounds of it so determinately marked, as that we shall be able to say, in all instances, where rigid right and justice end, and oppression begins. In like manner, it is impossible to determine how much of every man's income ought to be devoted to pious and charitable purposes: the boundaries cannot be exactly marked; yet we are at no loss in the ease of others to perceive the difference betwixt a liberal and generous man, and one of a hard-hearted and penurious disposition.

III. FROM THE DIFFICULTY WITH WHICH MEN ARE BROUGHT TO ACKNOWLEDGE THEIR FAULTS, EVEN WHEN CONSCIOUS THAT THEY HAVE DONE WRONG. We wish always to entertain a favourable opinion of ourselves and of our own conduct, and are displeased with those who endeavour in any instance to change this opinion, though it be done with the best, and most friendly intention. But how unreasonable is this degree of self-love! Were we alive to our true interests, we would wish to become better acquainted with our follies and our faults, and would esteem our faithful reprovers our best friends.

IV. FROM THE DISPOSITION WHICH MEN DISCOVER TO REST IN NOTIONS AND FORMS OF RELIGION, WHILE THEY ARE DESTITUTE OF ITS POWER. Hence it is that so many are hearers of the Word only, and not doers also, deceiving their own selves. Hence it is that so many shew great zeal about small and unimportant matters in religion, who are shamefully deficient in some of its plainest and most essential duties; that so many are punctual in their observance of religious institutions, who are unjust and uncharitable in their conduct towards their fellow creatures. Hypocrisy in all its forms and appearances flows from the deceitfulness of the heart for in general men deceive themselves before they attempt to deceive others.

V. WHEN MEN OVERLOOK THE REAL MOTIVES OF THEIR CONDUCT, AND MISTAKE THE WORKINGS OF THEIR OWN CORRUPTIONS FOR THE FRUITS OF THE SPIRIT OF GOD. We are greatly shocked when we read of the dreadful persecutions which in different ages have been carried on against the faithful servants of Christ; yet these men pretended zeal for the glory of God: nor is it improbable, but that many of them might so far deceive themselves as to imagine that they were doing God service, while shedding the blood of His saints. This is indeed the highest instance of the extreme deceitfulness and desperate wickedness of the human heart, and the most awful proof of being given up of God to a reprobate mind. But, in a lesser degree, men frequently practise this kind of deceit upon themselves, ascribing to the Word and to the Spirit of God what is evidently the effect of their own ignorance, wickedness, and depravity.

(D. Black.)
