Bits of copy and paste from the article which can be read in its entirety here:
“The heart is deceitful above all things,
and desperately wicked.” Jeremiah 17:9True and faithful is the testimony of God. Men may amuse themselves and their fellow creatures with empty, high sounding descriptions of the dignity of human nature, and the all-sufficient powers of man; but every humble, every truly enlightened mind, will see and acknowledge the justness of the declaration in the text, that the heart is deceitful above all things, and desperately wicked.
This is a truth which, like many others in the word of God, can only be learned from experience. As long as we assent to it, merely because it is contained in the Scriptures, we are strangers to its nature, and cannot understand what it means. But, as in water face answers to face, so does the heart of man to man. Human nature in different ages and in different circumstances is still the same; and when, by means of the word, the secrets of our own hearts are made manifest, when we come to perceive the exact correspondence between the declarations of Scripture, and what passes within us, we are obliged to confess, that God is in it of a truth, since none but He who searches the hearts, and tries the thoughts of men, could know so perfectly the inward workings of our minds, and those numberless evils which are hidden from the view of all our fellow creatures…
I.
The deceitfulness of the heart is evident from men’s general ignorance of their own character…
…Here then, is one striking evidence of the deceitfulness of the heart. It produces ignorance of ourselves; it keeps men strangers to their own character; and makes them fatally presume that they are in friendship with God, while they are enemies to him in their minds and by wicked works.
II.
The deceitfulness of the heart appears from men’s general disposition on all occasions to justify their own conduct…
…They even learn to call their favorite vices by softer names. With them, 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. Strange infatuation! to think that by changing the names of vices, it is possible to change their nature; and that what is base and detestable in others, should be excusable only in ourselves!…
III.
That the deceitfulness of the heart appears from the difficulty with which men are brought to acknowledge their faults, even when conscious that they have done wrong…
…This necessarily follows from that disposition in human nature, to which I have already adverted, namely, the disposition on all occasions to justify our own conduct. Hence men in general are so backward to acknowledge their faults, and so displeased with those who are so faithful and friendly as to point them out. How few can bear to be told their faults! This is the sure and ready way to make most men your enemies, even though you administer the reproof in the gentlest, and most prudent manner. Instead of reflecting on their own conduct, which might convince them of the justice of what is laid to their charge, many, in these cases, set themselves immediately to discover the faults in their faithful reprovers, or in those, who, they suspect, may have informed them; and turning away their attention entirely from themselves, are only concerned to find equal, if not greater blemishes in others. Thus deceitful is the heart of man. We wish always to entertain a favorable opinion of ourselves and of our own conduct, and are displeased with those who endeavor in any instance to change this opinion, though it be done with the best, and most friendly intention…
IV.
The deceitfulness of the heart appears from the disposition which men discover to rest in mere 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 show 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; that so many can talk fluently and correctly on religious subjects, who are visibly under the dominion of evil tempers or evil habits; that so many are scrupulously exact in what regards the externals of religion, who are at no pains to cultivate its genuine spirit, or to perform its most substantial duties. Like the Pharisees of old, who paid tithes of anise, mint, and cummin, they neglect the weightier matters of the law, judgment, mercy, and faith…
V.
That the deceitfulness of the heart appears in the highest degree, 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…
Of this we have several examples in scripture. A striking instance of it occurs in the conduct of Jehu, who, when shedding the blood of Jezreel to serve the purposes of his own ambition, said exultingly to Jehonadab, ‘Come, see my zeal for the Lord!’ It is not improbable, that at the time he imagined himself to be influenced by zeal for God, though there cannot be a doubt, that in what he did he was actuated chiefly by the ‘love of power’. Our blessed Lord forewarns his disciples, that the time would come, when whoever killed them, would think that he did God service. In like manner as the prophet Isaiah had declared concerning the persecuted people of God in his time, “Listen to what the Lord says, you that fear him and obey him: “Because you are faithful to me, some of your own people hate you and will have nothing to do with you. They mock you and say, ‘Let the Lord show his greatness and save you, so that we may see you rejoice.’ But they themselves will be disgraced!” (Isaiah 66:5)
