Here, 1. David adores God as the God of nature and the author of his being: Thy hands have made me and fashioned me, Job 10:8. Every man is as truly the work of God’s hands as the first man was, Ps. 139:15, 16. “Thy hands have not only made me, and given me a being, otherwise I should never have been, but fashioned me, and given me this being, this noble and excellent being, endued with these powers and faculties;” and we must own that we are fearfully and wonderfully made. 2. He addresses himself to God as the God of grace, and begs he will be the author of his new and better being. God made us to serve him and enjoy him; but by sin we have made ourselves unable for his service and indisposed for the enjoyment of him; and we must have a new and divine nature, otherwise we had the human nature in vain; therefore David prays, “Lord, since thou hast made me by thy power for thy glory, make me anew by thy grace, that I may answer the ends of my creation and live to some purpose: Give me understanding, that I may learn thy commandments.” The way in which God recovers and secures his interest in men is by giving them an understanding; for by that door he enters into the soul and gains possession of it.
