11. God hath spoken once. The Psalmist considered that the only effectual method of abstracting the minds of men from the vain delusions in which they are disposed to trust, was bringing them to acquiesce implicitly and firmly in the judgment of God. Usually they are swayed in different directions, or inclined at least to waver, just as they observe things changing in the world;¹ but he brings under their notice a surer principle for the regulation of their conduct, when he recommends a deferential regard to God's Word. God himself "dwells in the light which is inaccessible," (1 Timothy 6:16;) and as none can come to him except by faith, the Psalmist calls our attention to his word, in which he testifies the truth of his divine and righteous government of the world. It is of great consequence that we be established in the belief of God's Word, and we are here directed to the unerring certainty which belongs to it. The passage admits of two interpretations; but the scope of it is plainly this, that God acts consistently with himself, and can never swerve from what he has said. Many understand David to say that God had spoken once and a second time; and that by this explicit and repeated assertion of his power and mercy, he had confirmed the truth beyond all possibility of contradiction. There is a passage much to the same effect in the thirty-third chapter of the book of Job, and fourteenth verse, where the same words are used, only the copulative is interposed. If any should prefer it, however, I have no objections to the other meaning -- God has spoken once; twice have I heard this. It agrees with the context, and suggests a practical lesson of great importance; for when God has once issued his word he never retracts: on the other hand, it is our duty to ponder on what he has said, long and deliberately; and the meaning of David will then be, that he considered the Word of God in the light of a decree, steadfast and irreversible, but that, as regarded his exercise in reference to it, he meditated upon it again and again, lest the lapse of time might obliterate it from his memory. But the simpler and preferable reading would seem to be, that God had spoken once and again. There is no force in the ingenious conjecture, that allusion may be made to God's having spoken once in the Law, and a second time in the Prophets. Nothing more is meant than that the truth referred to had been amply confirmed, it being usual to reckon anything certain and fixed which has been repeatedly announced. Here, however, it must be remembered, that every word which may have issued forth from God is to be received with implicit authority, and no countenance given to the abominable practice of refusing to receive a doctrine, unless it can be supported by two or three texts of Scripture. This has been defended by an unprincipled heretic among ourselves, who has attempted to subvert the doctrine of a free election, and of a secret providence. It was not the intention of David to say that God was tied down to the necessity of repeating what he might choose to announce, but simply to assert the certainty of a truth which had been declared in clear and unambiguous terms. In the context which follows, he exemplifies himself that deferential reverence and regard for the word of God which all should, but which so few actually do, extend to it.

We might just put together, in a connected form, the particular doctrines which he has singled out for special notice. It is essentially necessary, if we would fortify our minds against temptation, to have suitably exalted views of the power and mercy of God, since nothing will more effectually preserve us in a straight and undeviating course, than a firm persuasion that all events are in the hand of God, and that he is as merciful as he is mighty. Accordingly, David follows up what he had said on the subject of the deference to be yielded to the word, by declaring that he had been instructed by it in the power and goodness of God. Some understand him to say, that God is possessed of power to deliver his people, and of clemency imbuing him to exercise it. But he would rather appear to mean, that God is strong to put a restraint upon the wicked, and crush their proud and nefarious designs, but ever mindful of his goodness in protecting and defending his own children. The man who disciplines himself to the contemplation of these two attributes, which ought never to be dissociated in our minds from the idea of God, is certain to stand erect and immovable under the fiercest assaults of temptation; while, on the other hand, by losing sight of the all-sufficiency of God, (which we are too apt to do,) we lay ourselves open to be overwhelmed in the first encounter. The world's opinion of God is, that he sits in heaven an idle and unconcerned spectator of events which are passing. Need we wonder, that men tremble under every casualty, when they thus believe themselves to be the sport of blind chance? There can be no security felt unless we satisfy ourselves of the truth of a divine superintendence, and can commit our lives and all that we have to the hands of God. The first thing which we must look to is his power, that we may have a thorough conviction of his being a sure refuge to such as cast themselves upon his care. With this there must be conjoined confidence in his mercy, to prevent those anxious thoughts which might otherwise rise in our minds. These may suggest the doubt -- What though God govern the world? does it follow that he will concern himself about such unworthy objects as ourselves?

There is an obvious reason, then, for the Psalmist coupling these two things together, his power and his clemency. They are the two wings wherewith we fly upwards to heaven; the two pillars on which we rest, and may defy the surges of temptation. Does danger, in short, spring up from any quarter, then just let us call to remembrance that divine power which can bid away all harms, and as this sentiment prevails in our minds, our troubles cannot fail to fall prostrate before it. Why should we fear -- how can we be afraid, when the God who covers us with the shadow of his wings, is the same who rules the universe with his nod, holds in secret chains the devil and all the wicked, and effectually overrules their designs and intrigues?

The Psalmist adds, Thou wilt certainly render to every man according to his work. And here he brings what he said to bear still more closely upon the point which he would establish, declaring that the God who governs the world by his providence will judge it in righteousness. The expectation of this, duly cherished, will have a happy effect in composing our minds, allaying impatience, and checking any disposition to resent and retaliate under our injuries. In resting himself and others before the great bar of God, he would both encourage his heart in the hope of that deliverance which was coming, and teach himself to despise the insolent persecution of his enemies, when he considered that every man's work was to come into judgment before Him, who can no more cease to be Judge than deny himself. We can therefore rest assured, however severe our wrongs may be, though wicked men should account us the filth and the off-scourings of all things, that God is witness to what we suffer, will interpose in due time, and will not disappoint our patient expectation. From this, and passages of a similar kind, the Papists have argued, in defense of their doctrine, that justification and salvation depend upon good works; but I have already exposed the fallacy of their reasoning. No sooner is mention made of works, than they catch at the expression, as amounting to a statement that God rewards men upon the ground of merit. It is with a very different design than to encourage any such opinion, that the Spirit promises a reward to our works -- it is to animate us in the ways of obedience, and not to inflame that impious self-confidence which cuts up salvation by the very roots. According to the judgment which God forms of the works of the believer, their worth and valuation depend, first, upon the free pardon extended to him as a sinner, and by which he becomes reconciled to God; and, next, upon the divine condescension and indulgence which accepts his services,² notwithstanding all their imperfections. We know that there is none of our works which, in the sight of God, can be accounted perfect or pure, and without taint of sin. Any recompense they meet with must therefore be traced entirely to his goodness. Since the Scriptures promise a reward to the saints, with the sole intention of stimulating their minds, and encouraging them in the divine warfare, and not with the remotest design of derogating from the mercy of God, it is absurd in the Papists to allege that they, in any sense, merit what is bestowed upon them. As regards the wicked, none will dispute that the punishment awarded to them, as violators of the law, is strictly deserved.
