I Will Sing of the Mercies of the Lord

I Will Sing of the Mercies of the Lord was written by James H. Fillmore in the late nineteenth century. The hymn takes its text almost directly from Psalm 89:1, a verse that declares the believer’s resolve to continually sing of God’s steadfast love and proclaim His faithfulness across generations. Its simplicity and direct reliance on Scripture have made it one of the most enduring and widely sung choruses in both traditional and contemporary worship settings.

James H. Fillmore, a gifted composer and publisher, sought to produce music that could be easily learned and sung by congregations of all ages. This hymn reflects that goal beautifully. Its repetitive structure, short phrases, and memorable melody enable worshipers to join in quickly and to focus their hearts on the central theme: God’s mercy and faithfulness never fail. Because of its joyful tone and biblical foundation, the hymn became a favorite for Sunday schools, camp meetings, and evangelistic services, helping entire generations memorize and celebrate the words of Scripture through song.

The message of the hymn is timeless. It teaches believers to live in constant remembrance of God’s covenant love and to testify of His goodness openly. Singing of the Lord’s mercies is more than a musical act, it is an act of faith, gratitude, and witness. This hymn encourages Christians to proclaim God’s unchanging faithfulness not only in moments of blessing but also in times of trial, pointing every heart back to the truth that His mercy endures forever.
