The law of the Lord is perfect, restoring the soul. The commandment of the Lord is true, making the simple-minded wise.
The psalm moves from creation to God’s special revelation, His word. “The law” here is not merely a list of individual commandments, but the teaching God has revealed for human life. It is “perfect,” that is, complete and fully suited to its purpose. The phrase “restores the soul” means it renews a person, brings him back to the right path, and turns him toward God. The statement “the Lord’s commandment is true” shows that God’s word is trustworthy and does not mislead. It makes the simple-minded wise, helping them distinguish right from wrong and choose the path that pleases God. For the believer, this is a reminder that spiritual renewal is not based only on feelings. We need truth that corrects our thinking, shapes our priorities, and guides the course of life. Scripture not only reveals God, but also, when it is received with faith and obedience, renews a person and teaches him to live with wisdom.
