Psalms 51:3

Substantiation of the prayer by the consideration, that his sense of sin is more than superficial, and that he is ready to make a penitential confession. True penitence is not a dead knowledge of sin committed, but a living sensitive consciousness of it (Isa 59:12), to which it is ever present as a matter and ground of unrest and pain. This penitential sorrow, which pervades the whole man, is, it is true, no merit that wins mercy or favour, but it is the condition, without which it is impossible for any manifestation of favour to take place. Such true consciousness of sin contemplates sin, of whatever kind it may be, directly as sin against God, and in its ultimate ground as sin against Him alone (חטא with ל of the person sinned against, Isa 42:24; Mic 7:9); for every relation in which man stands to his fellow-men, and to created things in general, is but the manifest form of his fundamental relationship to God; and sin is "that which is evil in the eyes of God" (Isa 65:12; Isa 66:4), it is contradiction to the will of God, the sole and highest Lawgiver and Judge. Thus it is, as David confesses, with regard to his sin, in order that... This למען must not be weakened by understanding it to refer to the result instead of to the aim or purpose. If, however, it is intended to express intention, it follows close upon the moral relationship of man to God expressed in לך לבדּך and הרע בּעיניך, - a relationship, the aim of which is, that God, when He now condemns the sinner, may appear as the just and holy One, who, as the sinner is obliged himself to acknowledge, cannot do otherwise than pronounce a condemnatory decision concerning him. When sin becomes manifest to a man as such, he must himself say Amen to the divine sentence, just as David does to that passed upon him by Nat…

Though David penned this psalm upon a very particular occasion, yet, it is of as general use as any of David's psalms; it is the most eminent of the penitential psalms, and most expressive of the cares and desires of a repenting sinner. It is a pity indeed that in our devout addresses to God we should have any thing else to do than to praise God, for that is the work of heaven; but we make other work for ourselves by our own sins and follies: we must come to the throne of grace in the posture of penitents, to confess our sins and sue for the grace of God; and, if therein we would take with us words, we can nowhere find any more apposite than in this psalm, which is the record of David's repentance for his sin in the matter of Uriah, which was the greatest blemish upon his character: all the rest of his faults were nothing to this; it is said of him (Kg1 15:5), That "he turned not aside from the commandment of the Lord all the days of his life, save only in the matter of Uriah the Hittite." In this psalm, I. He confesses his sin (Psa 51:3-6). II. He prays earnestly for the pardon of his sin (Psa 51:1, Psa 51:2, Psa 51:7, Psa 51:9). III. For peace of conscience (Psa 51:8, Psa 51:12). IV. For grace to go and sin no more (Psa 51:10, Psa 51:11, Psa 51:14). V. For liberty of access to God (Psa 51:15). IV. He promises to do what he could for the good of the souls of others (Psa 51:13) and for the glory of God (Psa 51:16, Psa 51:17, Psa 51:19). And, lastly, concludes with a prayer for Zion and Jerusalem (Psa 51:18). Those whose consciences charge them with any gross sin should, with a believing regard to Jesus Christ, the Mediator, again and again pray over this psalm; nay, though we have not been guilty of adultery and murder, or any the like enormous crime, yet in singing it,…

51:3-6 The psalmist accepts the consequences of his sin against God. He knows that there is nothing good in him unless God renews his life.
