The Law Of The Lord Is Perfect
The law of the Lord is perfect, converting the soul; The testimony of the Lord is sure, making wise the simple. Psalm 19:7 NKJV
The psalmist gives an account of the excellent properties and uses of the word of God, in six sentences in each of which the name Jehovah is repeated, and no vain repetition, for the law has its authority and all its excellency from the law-maker. Here are six several titles of the word of God, to take in the whole of divine revelation, precepts and promises, and especially the gospel. Here are several good properties of it, which proves its divine original, which recommend it to our affection, and which extol it above all other laws whatsoever. Here are several good effects of the law upon the minds of men, which show what it is designed for, what use we are to make of it, and how wonderful the efficacy of divine grace is, going along with it, and working by it.
The law of the Lord is perfect. It is perfectly free from all corruption, perfectly filled with all good, and perfectly fitted for the end for which it is designed; and it will make the man of God perfect, 2 Tim. 3:17 . Nothing is to be added to it nor taken from it. It is of use to convert the soul, to bring us back to ourselves, to our God, to our duty; for it shows us our sinfulness and misery in our departures from God and the indispensable necessity of our return to him.
The testimony of the Lord (which witnesses for him to us) is sure, incontestably and inviolably sure, what we may give credit to, may rely upon, and may be confident it will not deceive us. It is a sure discovery of the divine truth, a sure direction in the way of duty. It is a sure foundation of living comforts and a sure foundation of lasting hopes. It is of use to make us wise, wise to salvation, 2 Tim. 3:15 . It will give us an insight into things divine and a foresight of things to come. It will employ us in the best work and secure to us our true interests. It will make even the simple (poor contrivers as they may be for the present world) wise for their souls and eternity. Those that are humbly simple, sensible of their own folly and willing to be taught, shall be made wise by the word of God, Psalm 25:9. The statutes of the Lord (enacted by his authority, and binding on all wherever they come) are right, exactly agreeing with the eternal rules and principles of good and evil, that is, with the right reason of man and the right counsels of God. All God’s precepts, concerning all things, are right (Psalm 119:128 ), just as they should be; and they will set us to rights if we receive them and submit to them; and, because they are right, they rejoice the heart. The law, as we see it in the hands of Christ, gives cause for joy; and, when it is written in our hearts, it lays a foundation for everlasting joy, by restoring us to our right mind.
The commandment of the Lord is pure; it is clear, without darkness; it is clean, without dross and defilement. It is itself purified from all alloy, and is purifying to those that receive and embrace it. It is the ordinary means which the Spirit uses in enlightening the eyes; it brings us to a sight and sense of our sin and misery, and directs us in the way of duty.
The fear of the Lord (true religion and godliness prescribed in the word, reigning in the heart, and practiced in the life) is clean, clean itself, and will make us clean (Jn. 15:3 ); it will cleanse our way, Psalm 119:9 . And it endureth for ever; it is of perpetual obligation and can never be repealed. The ceremonial law is long since done away, but the law concerning the fear of God is ever the same. Time will not alter the nature of moral good and evil.
The judgments of the Lord (all his precepts, which are framed in infinite wisdom) are true; they are grounded upon the most sacred and unquestionable truths; they are righteous, all consonant to natural equity; and they are so altogether: there is no unrighteousness in any of them, but they are all of a piece. He expresses the great value he had for the word of God, and the great advantage he had, and hoped to have, from it. - Matthew Henry
