The psalmist here shows that godly people are happy people; they are, and shall be, blessed indeed. Felicity is the thing we all pretend to aim at and pursue. He does not say here wherein it consists; it is enough for us to know what we must do and be that we may attain to it, and that we are here told. All men would be happy, but few take the right way; God has here laid before us the right way, which we may be sure will end in happiness, though it be strait and narrow. Blessednesses are to the righteous; all manner of blessedness. Now observe the characters of the happy people. Those are happy, 1. Who make the will of God the rule of all their actions, and govern themselves, in their whole conversation, by that rule: They walk in the law of the Lord, Psa 119:1. God's word is a law to them, not only in this or that instance, but in the whole course of their conversation; they walk within the hedges of that law, which they dare not break through by doing any thing it forbids; and they walk in the paths of that law, which they will not trifle in, but press forward in them towards the mark, taking every step by rule and never walking at all adventures. This is walking in God's ways (Psa 119:3), the ways which he has marked out to us and has appointed us to walk in. It will not serve us to make religion the subject of our discourse, but we must make it the rule of our walk; we must walk in his ways, not in the way of the world, or of our own hearts, Job 23:10, Job 23:11; Job 31:7. 2. Who are upright and honest in their religion - undefiled in the way, not only who keep themselves pure from the pollutions of actual sin, unspotted from the world, but who are habitually sincere in their intentions, in whose spirit there is no guile, who are really as good as they seem to be and row the same way as they look. 3. Who are true to the trust reposed in them as God's professing people. It was the honour of the Jews that to them were committed the oracles of God; and blessed are those who preserve pure and entire that sacred deposit, who keep his testimonies as a treasure of inestimable value, keep them as the apple of their eye, so keep them as to carry the comfort of them themselves to another world and leave the knowledge and profession of them to those who shall come after them in this world. Those who would walk in the law of the Lord must keep his testimonies, that is, his truths. Those will not long make conscience of good practices who do not adhere to good principles. Or his testimonies may denote his covenant; the ark of the covenant is called the ark of the testimony. Those do not keep covenant with God who do not keep the commandments of God. 4. Who have a single eye to God as their chief good and highest end in all they do in religion (Psa 119:2): They seek him with their whole heart. They do not seek themselves and their own things, but God only; this is that which they aim at, that God may be glorified in their obedience and that they may be happy in God's acceptance. he is, and will be, the rewarder, the reward, of all those who thus seek him diligently, seek him with the heart, for that is it that God looks at and requires; and with the whole heart, for if the heart be divided between him and the world it is faulty. 5. Who carefully avoid all sin (Psa 119:3): They do no iniquity; they do not allow themselves in any sin; they do not commit it as those do who are the servants of sin; they do not make a practice of it, do not make a trade of it. They are conscious to themselves of much iniquity that clogs them in the ways of God, but not of that iniquity which draws them out of those ways. Blessed and holy are those who thus exercise themselves to have always consciences void of offence.

Blessed are they that keep his testimonies,.... The whole word of God, the Scriptures of truth, are his testimonies: they testify of the mind of God, and of his love and grace in the method of salvation by Christ; they testify of Christ, his person, offices, and grace; of the sufferings of Christ, and the glory that should follow; and of all the happiness that comes to the people of God thereby. The law is called a testimony, which being put into the ark, that had the name of the ark of the testimony. This is a testimony of the perfections of God, his holiness, justice, and goodness displayed in it; and of his good and perfect will, what should or should not be done. The Gospel is the testimony of Christ, of what he is, has done and suffered for his people, and of the blessings of grace by him; the ordinances of it, baptism and the Lord's supper, testify of the love of God, and grace of Christ; and all these good men keep: they keep the Scriptures as a sacred "depositum"; they hold fast the faithful word of the Gospel, that no man take it from them; and are desirous of observing both the law of God, as in the hands of Christ; and the ordinances of the Gospel, as delivered by him, from a principle of love to him; and such are happy persons in life, at death, and to all eternity;

and that seek him with the whole heart; that is, that seek the Lord by prayer and supplication, with a true heart, and in sincerity; that seek to know more of him, and that in good earnest; that seek for communion and fellowship with him, with the Spirit within them, with all their heart and soul; that seek Christ, and God in Christ, his kingdom, and his righteousness, and that in the first place, early, earnestly, and diligently. The Targum is,

"they seek his doctrine with the whole heart.''
