Psalms 19:8-10

8. The statutes of Jehovah are right. The Psalmist at first view may seem to utter a mere common-place sentiment when he calls the statutes of the Lord right. If we, however, more attentively consider the contrast which he no doubt makes between the rectitude of the law and the crooked ways in which men entangle themselves when they follow their own understandings, we will be convinced that this commendation implies more than may at first sight appear. We know how much every man is wedded to himself, and how difficult it is to eradicate from our minds the vain confidence of our own wisdom. It is therefore of great importance to be well convinced of this truth, that a man’s life cannot be ordered aright unless it is framed according to the law of God, and that without this he can only wander in labyrinths and crooked bypaths. David adds, in the second place, that God’s statutes rejoice the heart. This implies that there is no other joy true and solid but that which proceeds from a good conscience; and of this we become partakers when we are certainly persuaded that our life is pleasing and acceptable to God. No doubt, the source from which true peace of conscience proceeds is faith, which freely reconciles us to God. But to the saints who serve God with true affection of heart there arises unspeakable joy also, from the knowledge that they do not labor in his service in vain, or without hope of recompense, since they have God as the judge and approver of their life. In short, this joy is put in opposition to all the corrupt enticements and pleasures of the world, which are a deadly bait, luring wretched souls to their everlasting destruction. The import of the Psalmist’s language is, Those who take delight in committing sin procure for themselves abundant matter of sorrow; but the observance of the law of God, on the contrary, brings to man true joy. In the end of the verse, the Psalmist teaches that the commandment of God is pure, enlightening the eyes By this he gives us tacitly to understand that it is only in the commandments of God that we find the difference between good and evil laid down, and that it is in vain to seek it elsewhere, since whatever men devise of themselves is mere filth and refuse, corrupting the purity of the life. He farther intimates that men, with all their acuteness, are blind, and always wander in darkness, until they turn their eyes to the light of heavenly doctrine. Whence it follows, that none are truly wise but those who take God for their conductor and guide, following the path which he points out to them, and who are diligently seeking after the peace which he offers and presents by his word.

But here a question of no small difficulty arises; for Paul seems entirely to overthrow these commendations of the law which David here recites. How can these things agree together: that the law restores the souls of men, while yet it is a dead and deadly letter? that it rejoices men’s hearts, and yet, by bringing in the spirit of bondage, strikes them with terror? that it enlightens the eyes, and yet, by casting a veil before our minds, excludes the light which ought to penetrate within? But, in the first place, we must remember what I have shown you at the commencement, that David does not speak simply of the precepts of the Moral Law, but comprehends the whole covenant by which God had adopted the descendants of Abraham to be his peculiar people; and, therefore, to the Moral Law, the rule of living well — he joins the free promises of salvation, or rather Christ himself, in whom and upon whom this adoption was founded. But Paul, who had to deal with persons who perverted and abused the law, and separated it from the grace and the Spirit of Christ, refers to the ministry of Moses viewed merely by itself, and according to the letter. It is certain, that if the Spirit of Christ does not quicken the law, the law is not only unprofitable, but also deadly to its disciples. Without Christ there is in the law nothing but inexorable rigour, which adjudges all mankind to the wrath and curse of God. And farther, without Christ, there remains within us a rebelliousness of the flesh, which kindles in our hearts a hatred of God and of his law, and from this proceed the distressing bondage and awful terror of which the Apostle speaks. These different ways in which the law may be viewed, easily show us the manner of reconciling these passages of Paul and David, which seem at first view to be at variance. The design of Paul is to show what the law can do for us, taken by itself; that is to say, what it can do for us when, without the promise of grace, it strictly and rigorously exacts from us the duty which we owe to God; but David, in praising it as he here does, speaks of the whole doctrine of the law, which includes also the gospel, and, therefore, under the law he comprehends Christ.
