(9) Who can say, I have made my heart clean?--Though we may have done our best by self-examination and confession, and repentance and trust in the atoning blood of Christ to obtain remission of sin, still the heart is so deceitful (Jeremiah 17:9), sins may so easily have escaped our notice (Psalm 19:12, 1Corinthians 4:4), that satisfaction with ourselves ought never to be allowed (Romans 11:20).

Verse 9. - Who can say, I have made my heart clean, I am pure from my sin? The question implies the answer, "No one." This is expressed in Job 14:4, "Who can bring a clean thing out of an unclean? not one." At the dedication of the temple, Solomon enunciates this fact of man's corruption, "There is no man that sinneth not" (1 Kings 8:46). The prophet testifies, "The heart is deceitful above all things, and it is desperately sick: who can know it?" (Jeremiah 17:9). And St. John warns, "If we say that we have no sin, we deceive ourselves, and the truth is not in us" (1 John 1:8). The heart is cleansed by self-examination and repentance; but it is so easy to deceive one's self in this matter, sins may lurk undetected, motives may be overlooked, so that no one can rightly be self-righteous, or conceited, or proud of his spiritual state. The "my sin" at the end of the clause is rather possible than actual sin; and the expression means that no one can pride himself on being secure from yielding to temptation, however clean for a time his conscience may be. The verse, therefore, offers a stern corrective of two grievous spiritual errors - presumption and apathy.

20:7. A good man is not liable to uneasiness in contriving what he shall do, or in reflecting on what he has done, as those who walk in deceit. And his family fare better for his sake. 8. If great men are good men, they may do much good, and prevent very much evil. 9. Some can say, Through grace, we are cleaner than we have been; but it was the work of the Holy Spirit. 10. See the various deceits men use, of which the love of money is the root. The Lord will not bless what is thus gotten. 11. Parents should observe their children, that they may manage them accordingly. 12. All our powers and faculties are from God, and are to be employed for him. 13. Those that indulge themselves, may expect to want necessaries, which should have been gotten by honest labour. 14. Men use arts to get a good bargain, and to buy cheap; whereas a man ought to be ashamed of a fraud and a lie. 15. He that prefers true knowledge to riches, follows the ways of religion and happiness. If we really believed this truth, the word of God would be valued as it deserves, and the world would lose its tempting influence. 16. Those ruin themselves who entangle themselves in rash suretiship. Also those who are in league with abandoned women. Place no confidence in either. 17. Wealth gotten by fraud may be sweet, for the carnal mind takes pleasure in the success of wicked devices; but it will be bitter in the reflection. 18. Especially we need advice in spiritual warfare. The word and Spirit of God are the best counsellors in every point. 19. Those dearly buy their own praise, who put confidence in a man because he speaks fairly. 20. An undutiful child will become very miserable. Never let him expect any peace or comfort. 21. An estate suddenly raised, is often as suddenly ruined. 22. Wait on the Lord, attend his pleasure, and he will protect thee.Who can say, I have made my heart clean,.... The heart of than is naturally unclean, the mind, conscience, understanding, will, and affections; there is no part clean, all are defiled with sin; and though there is such a thing as a pure or clean heart, yet not as made so by men; it is God that has made the heart, that can only make it clean, or create a clean heart in men; it is not to be done by themselves, or by anything that they can do; it is done only by the grace of God, and blood of Christ: God has promised to do it, and he does it; and to him, and to him only, is it to be ascribed;

I am pure from my sin? the sin of nature or of action: such indeed who are washed from their sins in the blood of Christ; whose sins are all pardoned for his sake, and who are justified from all things by his righteousness; they are pure from sin, none is to be seen in them, or found upon them in a legal sense: they are all fair and comely, and without fault in the sight of God; their iniquities are caused to pass from them; and they are clothed with fine linen, clean and white, the righteousness of the saints: but then none are pure from indwelling sin, nor from the commission of sin; no man can say this, any more than the former; if he does, he is an ignorant man, and does not know the plague of his heart; and he is a vain pharisaical man; yea, a man that does not speak the truth, nor is the truth in him, 1 John 1:8.
