The {f} law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple.

(f) Though the creatures cannot serve, yet this should be sufficient to lead us to him.

Wesley's Notes

19:7 The law - The doctrine delivered to his church, whether by Moses, or by other prophets. Having discoursed hitherto of the glory of God shining forth in, the visible heavens, he now proceeds to another demonstration of God's glory, which he compares with and prefers before the former. Perfect - Completely discovering both the nature and will of God, and the whole duty of man, what he is to believe and practice, and whatsoever is necessary to his present and eternal happiness. Whereas the creation, although it did declare so much of God, as left all men without excuse, yet did not fully manifest the will of God, nor bring men to eternal salvation. Converting - From sin to God, from whom all men are naturally revolted. Testimony - His law, so called because it is a witness between God and man, what God requires of man, and what upon the performance of that condition, he will do for man. Sure - Heb. faithful or true, which is most necessary in a witness: it will not mislead any man, but will infallibly bring him to happiness. Simple - Even persons of the lowest capacities.

Jamieson-Fausset-Brown Bible Commentary

7-9. The law is described by six names, epithets, and effects. It is a rule, God's testimony for the truth, His special and general prescription of duty, fear (as its cause) and judicial decision. It is distinct and certain, reliable, right, pure, holy, and true. Hence it revives those depressed by doubts, makes wise the unskilled (2Ti 3:15), rejoices the lover of truth, strengthens the desponding (Ps 13:4; 34:6), provides permanent principles of conduct, and by God's grace brings a rich reward.

Matthew Henry's Concise Commentary

19:7-10 The Holy Scripture is of much greater benefit to us than day or night, than the air we breathe, or the light of the sun. To recover man out of his fallen state, there is need of the word of God. The word translated law, may be rendered doctrine, and be understood as meaning all that teaches us true religion. The whole is perfect; its tendency is to convert or turn the soul from sin and the world, to God and holiness. It shows our sinfulness and misery in departing from God, and the necessity of our return to him. This testimony is sure, to be fully depended on: the ignorant and unlearned believing what God saith, become wise unto salvation. It is a sure direction in the way of duty. It is a sure fountain of living comforts, and a sure foundation of lasting hopes. The statues of the Lord are right, just as they should be; and, because they are right, they rejoice the heart. The commandments of the Lord are pure, holy, just, and good. By them we discover our need of a Saviour; and then learn how to adorn his gospel. They are the means which the Holy Spirit uses in enlightening the eyes; they bring us to a sight and sense of our sin and misery, and direct us in the way of duty. The fear of the Lord, that is, true religion and godliness, is clean, it will cleanse our way; and it endureth for ever. The ceremonial law is long since done away, but the law concerning the fear of God is ever the same. The judgments of the Lord, his precepts, are true; they are righteous, and they are so altogether; there is no unrighteousness in any of them. Gold is only for the body, and the concerns of time; but grace is for the soul, and the concerns of eternity. The word of God, received by faith, is more precious than gold; it is sweet to the soul, sweeter than honey. The pleasure of sense soon surfeit, yet never satisfy; but those of religion are substantial and satisfying; there is no danger of excess.
