Serve the Lord with gladness - That is, In your worship, and in all your acts of obedience. Let there be joy in this service. Let it not be with the fear of slaves; not as a matter of compulsion and force; not with reluctance, moroseness, or gloom. Let it be a cheerful, happy service; let it be freely rendered, let it be an occasion of joy to the soul. The service of God is a source of the highest joy that man knows.

Come before his presence with singing - As expressive of joy. So the birds sing; so nature rejoices; so should man - intelligent, redeemed, immortal man, be joyful.

Serve the Lord with gladness - It is your privilege and duty to be happy in your religious worship. The religion of the true God is intended to remove human misery, and to make mankind happy. He whom the religion of Christ has not made happy does not understand that religion, or does not make a proper use of it.

Serve the Lord with gladness,.... Not with a slavish fear, under a spirit of bondage, as the Jews under the legal dispensation; not in the oldness of the letter, but in the newness of the Spirit: with spiritual joy and freedom of soul, as under the spirit of adoption; readily, willingly, cheerfully; without sinister and selfish ends and views; as their Lord and Master; taking delight in his person, and pleasure in his service; rejoicing in him, without having any confidence in the flesh:

come before his presence with singing; to the throne of his grace with thankfulness for mercies received, as well as to implore others; and into his house, and at his ordinances, beginning public worship with singing psalms, hymns, and spiritual songs; see Psalm 95:2.

Serve the LORD with gladness: come before his presence with singing.

100:1-5 An exhortation to praise God, and rejoice in him. - This song of praise should be considered as a prophecy, and even used as a prayer, for the coming of that time when all people shall know that the Lord he is God, and shall become his worshippers, and the sheep of his pasture. Great encouragement is given us, in worshipping God, to do it cheerfully. If, when we strayed like wandering sheep, he has brought us again to his fold, we have indeed abundant cause to bless his name. The matter of praise, and the motives to it, are very important. Know ye what God is in himself, and what he is to you. Know it; consider and apply it, then you will be more close and constant, more inward and serious, in his worship. The covenant of grace set down in the Scriptures of the Old and New Testament, with so many rich promises, to strengthen the faith of every weak believer, makes the matter of God's praise and of his people's joys so sure, that how sad soever our spirits may be when we look to ourselves, yet we shall have reason to praise the Lord when we look to his goodness and mercy, and to what he has said in his word for our comfort.
