If thou, O God! shoudst mark iniquities [1] Here the Prophet acknowledges that although grievously afflicted, he had justly deserved such punishment, as had been inflicted upon him. As by his own example he gives a rule which the whole Church ought to observe, let no man presume to intrude himself into the presence of God, but in the way of humbly deprecating his wrath; and especially when God exercises severity in his dealings towards us, let us know that we are required to make the same confession which is here uttered. Whoever either flatters himself or buries his sins by inattention to them, deserves to pine away in his miseries; at least he is unworthy of obtaining from God the smallest alleviation. Whenever God then exhibits the tokens of his wrath, let even the man who seems to others to be the holiest of all his fellows, descend to make this confession, that should God determine to deal with us according to the strict demands of his law, and to summon us before his tribunal, not one of the whole human race would be able to stand. We grant that it is one man only who here prays, but he at once pronounces sentence upon the whole human race. "All the children of Adam," he substantially says, "from the first to the last, are lost and condemned, should God require them to render up an account of their life." It is therefore necessary that even the holiest of men should pass under this condemnation, that they may betake themselves to the mercy of God as their only refuge. The Prophet does not however mean to extenuate his own fault by thus involving others with himself, as we see hypocrites do, who when they dare not altogether justify themselves, resort to this subterfuge, "Am I the first or the only man who has offended?" and thus, mingling themselves with a multitude of others, they think themselves half absolved from their guilt. But the Prophet, instead of seeking to shelter himself under such a subterfuge, rather confesses, after having thoroughly examined himself, that if of the whole human race not even one can escape eternal perdition, this instead of lessening rather increased his obnoxiousness to punishment. Whoever, as if he had said, shall come into the presence of God, whatever may be his eminence for sanctity, he must succumb and stand confounded, [2] what then will be the case as to me, who am not one of the best? The right application of this doctrine is, for every man to examine in good earnest his own life by the perfection which is enjoined upon us in the law. In this way he will be forced to confess that all men without exception have deserved everlasting damnation; and each will acknowledge in respect to himself that he is a thousand times undone. Farther, this passage teaches us that, since no man can stand by his own works, all such as are accounted righteous before God, are righteous in consequence of the pardon and remission of their sins. In no other manner can any man be righteous in the sight of God. Very differently do the Papists think. They indeed confess that the deficiencies of our works are supplied by the lenity which God exercises towards us; but at the same time they dream of a partial righteousness, on the ground of which men may stand before God. In entertaining such an idea they go very far astray from the sense of the Prophet, as will appear more plainly from the sequel.

Footnotes

1 - The allusion is to judicial proceedings. It is as if the Psalmist had said, If thou wert, like an earthly judge, to note down every minute circumstance of guilt, who would be able to stand such a trial, or leave thy court unconvicted, or uncondemned? The verb, "smr, denotes not only to mark, or observe, but to observe diligently, so as to retain a perpetual memory of what is done amiss a rigid and judicial observation of faults: see Job 10:14; Job 14:16, 17 " Phillips.

If thou, Lord, shouldest mark iniquities - If thou shouldst observe, note, attend to, regard all the evil that I have done. The Hebrew word means properly to keep, to watch, to guard. The word, as used here, refers to that kind of vigilance or watchfulness which one is expected to manifest who is on guard; who keeps watch in a city or camp by night. The idea is, If God should thus look with a scrutinizing eye; if he should try to see all that he could see; if he should suffer nothing to escape his observation; if he should deal with us exactly as we are; if he should overlook nothing, forgive nothing, we could have no hope.
Who shall stand? - Who shall stand upright? Who could stand before thee? Who could hope to be acquitted? This implies
(1) that the petitioner was conscious of guilt, or knew that he was a sinner;
(2) that he felt there was a depth of depravity in his heart which God could see, but which he did not - as every man must be certain that there is in his own soul;
(3) that God had the power of bringing that to light if he chose to do it, so that the guilty man would be entirely overwhelmed;
(4) that he who urged the prayer rested his only hope on the fact that God would not mark iniquity; would not develop what was in him; would not judge him by what he saw in his heart; but would deal with him otherwise, and show him mercy and compassion.
Every man must feel that if God should "mark iniquity" as it is - if he should judge us as we are - we could have no hope. It is only on the ground that we may be forgiven, that we eau hope to come before him.

If thou - shouldest mark iniquities - If thou shouldst set down every deviation in thought, word, and deed from thy holy law; and if thou shouldst call us into judgment for all our infidelities, both of heart and life; O Lord, who could stand? Who could stand such a trial, and who could stand acquitted in the judgment? This is a most solemn saying; and if we had not the doctrine that is in the next verse, who could be saved?

If thou, LORD, shouldest mark iniquities, O Lord, (b) who shall stand?
(b) He declares that we cannot be just before God but by forgiveness of sins.

If thou, Lord, shouldest mark iniquities,.... Or "observe" (f) them. Not but that God does observe the sins of men: he sees all the evil actions of bad men done in the dark, which cannot hide them from him; and all the iniquities of good men, so as to correct and chastise for them, but not with his eye of vindictive justice. Or "keep" (g) them; should he keep a watchful eye over them, make strict inspection into them, enter into a critical examination of them, and of all their aggravated circumstances; should he keep them in mind and memory, retain them in the book of his remembrance; should he lay them up, and keep them sealed among his stores, in order to be brought to light, and brought out as charges another day, and to the condemnation of men; should he set them before him in the light of his countenance, and not cast them behind his back and into the depths of the sea; should he visit for them in a way of wrath, or enter into judgment on account of them, with men in their own persons; demanding satisfaction for them at their own hands, without any regard to the sacrifice and satisfaction of his Son; all a man's righteousness, repentance, humiliation and tears, would stand him in no stead, would not answer for him, or atone for his sins; still his iniquities would remain marked before God; the consequence of which would be eternal damnation, Jeremiah 2:22;
O Lord, who shall stand? Not one; since all are sinners. The Arabic version adds, "before thee"; in his presence; in the house and courts of God, there to minister before him; to pray and praise, to preach and hear: or at his bar hereafter, with any boldness and confidence; so as to litigate the point with him in his court of judicature, before angels and men, and so as to carry the cause; the wicked shall not stand in judgment, Psalm 1:5. Or who can stand before his vindictive justice, or bear his wrath and vengeance? No one can. See Nahum 1:6, Malachi 3:2.
(f) "observaveris", V. L. Pagninus, Montanus, Musculus, Junius & Tremellius, Piscator, Michaelis. (g) "Serves", Cocceius; "servaveris", Muis.

shouldest mark--or, "take strict account" (Job 10:14; Job 14:16), implying a confession of the existence of sin.
who shall stand-- (Psalm 1:6). Standing is opposed to the guilty sinking down in fear and self-condemnation (Malachi 3:2; Revelation 6:15-16). The question implies a negative, which is thus more strongly stated.

Mark - Observe them accurately and punish them as they deserve. Stand - At thy tribunal.
