Psalms 51:4

Here the words before us are quoted in proof of the doctrine that God’s righteousness is apparent even in the sins of men, and his truth in their falsehood. To have a clear apprehension of their meaning, it is necessary that we reflect upon the covenant which God had made with David. The salvation of the whole world having been in a certain sense deposited with him by this covenant, the enemies of religion might take occasion to exclaim upon his fall, “Here is the pillar of the Church gone, and what is now to become of the miserable remnant whose hopes rested upon his holiness? Once nothing could be more conspicuous than the glory by which he was distinguished, but mark the depth of disgrace to which he has been reduced! Who, after so gross a fall, would look for salvation from his seed?” Aware that such attempts might be made to impugn the righteousness of God, David takes this opportunity of justifying it, and charging himself with the whole guilt of the transaction. He declares that God was justified when he spoke — not when he spoke the promises of the covenant, although some have so understood the words, but justified should he have spoken the sentence of condemnation against him for his sin, as he might have done but for his gratuitous mercy. Two forms of expression are here employed which have the same meaning, that thou mayest be justified when thou speakest, and be clear when thou judgest. As Paul, in the quotation already referred to, has altered the latter clause, and may even seem to have given a new turn to the sentiment contained in the verse, I shall briefly show how the words were applicable to the purpose for which they were cited by him. He adduces them to prove that God’s faithfulness remained unaffected by the fact that the Jews had broken his covenant, and fallen from the grace which he had promised. Now, at first sight it may not appear how they contain the proof alleged. But their appositeness will at once be seen if we reflect upon the circumstance to which I have already adverted. Upon the fall of one who was so great a pillar in the Church, so illustrious both as a prophet and a king, as David, we cannot but believe that many were shaken and staggered in the faith of the promises. Many must have been disposed to conclude, considering the close connection into which God had adopted David, that he was implicated in some measure in his fall. David, however, repels an insinuation so injurious to the divine honor, and declares, that although God should cast him headlong into everlasting destruction, his mouth would be shut, or opened only to acknowledge his unimpeachable justice. The sole departure which the apostle has made from the passage in his quotation consists in his using the verb to judge in a passive sense, and reading, that thou mightest overcome, instead of, that thou mightest be clear. In this he follows the Septuagint, and it is well known that the apostles do not study verbal exactness in their quotations from the Old Testament. It is enough for us to be satisfied, that the passage answers the purpose for which it was adduced by the apostle. The general doctrine which we are taught from the passage is, that whatever sins men may commit are chargeable entirely upon themselves, and never can implicate the righteousness of God. Men are ever ready to arraign his administration, when it does not correspond with the judgment of sense and human reason. But should God at any time raise persons from the depth of obscurity to the highest distinction, or, on the other hand, allow persons who occupied a most conspicuous station to be suddenly precipitated from it, we should learn from the example which is here set before us to judge of the divine procedure with sobriety, modesty, and reverence and to rest satisfied that it is holy, and that the works of God, as well as his words, are characterised by unerring rectitude. The conjunction in the verse, that-that thou mayest be justified, denotes not so much cause as consequence. It was not the fall of David, properly speaking, which caused the glory of God’s righteousness to appear. And yet, although men when they sin seem to obscure his righteousness, it emerges from the foul attempt only more bright than ever, it being the peculiar work of God to bring light out of darkness.
