Sing joyfully to God, all the earth: serve ye the Lord with gladness. Come in before his presence with exceeding great joy.

“"O serve the Lord with gladness" (ver. 2): he addresseth you, whoever ye are who endure all things in love, and rejoice in hope. "Serve the Lord," not in the bitterness of murmuring, but in the "gladness of love." "Come before His presence with rejoicing." It is easy to rejoice outwardly: rejoice before the presence of God. Let not the tongue be too joyful: let the conscience be joyful. "Come before His presence with a song."”

“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 Psa 95:2.”
