This Psalm is to exhort the children of God to follow Godliness and a holy life and the prescribing of the rule on how to form this worship in our hearts so we may devote ourselves wholly to the study of the law. The doctrine here should be carefully studied and treasured in our heart. Mankind ought to seek for no other rule for the perfecting of holiness but what consists in regulating their lives by rendering obedience.
All men seek happiness, but instead of seeking in the right path, they wander up and down.
The holy spirit condemns this apathy and blindness. THEY-not those who are wise in their own conceit, or assume a fantastical holiness, but those who dedicate themselves to the covenant of God, and yield obedience to the dictates of His law. This is to teach us that our life must be entirely under the direction of God. The law of God is an antidote to all deliquencies because it keeps our vicious propensities in check. Those who are instructed in the law of God can not set up the plea of ignorance when they fall into sin, they are willfully blind.
