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.
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.
