Psalms 19:7

The law of the Lord is perfect, converting the soul— {Restoring / Refreshing} the soul. The connection seems to be this: From the mighty scene and prospect of nature in the former verses, the Psalmist turns his thoughts to the consideration of the still greater works of grace. The rational world, as in itself the noblest, so has it been the more peculiar care of Providence to preserve and adorn it. The sun knows its course, and has always trod the path marked out by its Creator. The sea keeps its old channel, and in its utmost fury remembers the first law of its Maker, hitherto shalt thou go, and no further. But freedom and reason, subject to no such restraint, have produced infinite variety in the rational world. Of all the creatures, man only could forget his Maker and himself, and prostitute the honour of both by robbing God of the obedience due to him, and by submitting himself a slave to the elements of the world. When he looked up to the heavens, and saw the glory of the sun and stars, instead of praising the Lord of all, he foolishly said, "These are thy gods, O man!" When man was thus lost in ignorance and superstition, God manifested himself again, gave him a law to direct his will and inform his reason, and to teach him in all things how to pursue his happiness [and grace to fulfil that law, and obtain that happiness]. This was a kind of second creation; a work which calls as much both for our wonder and our praise as any or all the works of nature [and much more]; and thus the holy Psalmist sings the triumphs of grace, and extols the mercy and power of God, in restoring mankind from the bondage of ignorance and idolatry. The law of the Lord is perfect, &c. To this divine law the sinner owes the conversion of his soul; to the light of God's word the simple owes his wisdom; nay, even the pleasures of life and all the solid comforts we enjoy flow from the same living stream: The statutes of the Lord do rejoice the heart, as well as enlighten the eyes; and not only shew us the dangers and miseries of iniquity, and, by shewing, teach us to avoid them, but do lead us likewise to certain happiness and joy for evermore: for in keeping them there is great reward.
