Into this dreary life Nathan's message comes with merciful rebuke. The prompt severity of David's judgment against the selfish sinner of the inimitable apologue may be a subtle indication of his troubled conscience, which fancies some atonement for his own sin in stern repression of that of others; for consciousness of evil may sometimes sting into harshness as well as soften to lenity, and sinful man is a sterner judge than the righteous God. The answer of Nathan is a perfect example of the Divine way of convincing of sin. There is first the plain charge pressed home on the individual conscience, "Thou art the man." Then follows, not reproach nor further deepening of the blackness of the deed, but a tender enumeration of God's great benefits, whereon is built the solemn question, "Wherefore hast thou despised the commandment of the Lord, to do evil in His sight?" The contemplation of God's faithful love, and of the all-sufficient gifts which it bestows, makes every transgression irrational as well as ungrateful, and turns remorse, which consumes like the hot wind of the wilderness, into tearful repentance which refreshes the soul. When God has been seen loving and bestowing ere He commands and requires, it is profitable to hold the image of the man's evil in all its ugliness close up to his eyes; and so the bald facts are repeated next in the fewest, strongest words. Nor can the message close until a rigid law of retribution has been proclaimed, the slow operation of which will filter bitterness and shame through all his life. "And David said unto Nathan, I have sinned against the Lord." Two words (in the Hebrew) make the transition from sullen misery to real though shaded peace. No lengthened outpouring, no accumulation of self-reproach; he is too deeply moved for many words, which he knows God does not need. More would have been less. All is contained in that one sob, in which the whole frostwork of these weary months breaks up and rolls away, swept before the strong flood. And as brief and simple as the confession, is the response, "And Nathan said unto David, The Lord also hath put away thy sin." How full and unconditional the blessing bestowed in these few words; how swift and sufficient the answer! So the long estrangement is ended. Thus simple and Divine is the manner of pardon. In such short compass may the turning point of a life lie! But while confession and forgiveness heal the breach between God and David, pardon is not impunity, and the same sentence which bestows the remission of sin announces the exaction of a penalty. The judgments threatened a moment before--a moment so far removed now to David's consciousness that it would look as if an age had passed--are not withdrawn, and another is added, the death of Bathsheba's infant. God loves His servants too well to "suffer sin upon them," and the freest forgiveness and the happiest consciousness of it may consist with the loving infliction and the submissive bearing of pains, which are no longer the strokes of an avenging judge, but the chastisements of a gracious father.
The fifty-first psalm must, we think, be conceived of as following soon after Nathan's mission. There may be echoes of the prophet's stern question, "Wherefore hast thou despised the commandment of the Lord, to do evil in His sight?" and of the confession, "I have sinned against the Lord," in the words, "Against Thee, Thee only have I sinned, and done evil in Thy sight" (ver. 4), though perhaps the expressions are not so peculiar as to make the allusion certain. But, at all events, the penitence and prayers of the psalm can scarcely be supposed to have preceded the date of the historical narrative, which clearly implies that the rebuke of the seer was the first thing that broke up the dumb misery of unrepented sin.
