“Great Is Thy Faithfulness” is one of the beloved hymns in Christian worship, yet its origin is remarkably simple. Its author, Thomas Obadiah Chisholm, wrote the text in 1923 as a personal testimony to the unchanging faithfulness of the Lord across the ordinary seasons of life.

Chisholm was born in 1866 near Franklin, Kentucky, and his life followed a path familiar to many believers. He worked as a teacher, newspaper editor, and insurance agent, and for a time served as a Methodist minister. Chronic health problems eventually forced him to leave full time pastoral ministry, but this limitation did not weaken his faith. Instead, it deepened his awareness of God’s daily provision. Chisholm later explained that he had experienced no extraordinary miracles, only the continual evidence of God’s care, which he believed was more than enough reason for praise.

The scriptural foundation of the hymn comes directly from Lamentations 3:22-23 in the King James Version: “It is of the LORD’S mercies that we are not consumed, because his compassions fail not. They are new every morning: great is thy faithfulness.” These verses were written in the midst of national devastation and sorrow, yet they affirm God’s unchanging mercy. Chisholm drew from this passage to express a confidence that does not depend on circumstances, but on the character of God Himself.

After writing the poem, Chisholm sent it to his friend William Marion Runyan, a musician and editor associated with the Moody Bible Institute and Hope Publishing Company. Runyan composed the now familiar melody in Baldwin City, Kansas, and named the tune “Faithfulness.” The marriage of text and tune proved immediately effective. The steady, reassuring melody perfectly supported the message of God’s consistency, making the hymn easy to sing and deeply comforting to congregations.

What distinguishes this hymn from many other hymns is its focus on everyday grace. Rather than emphasizing dramatic deliverance or emotional intensity, the hymn points to the faithfulness seen in nature’s seasons, daily bread, forgiveness of sins, and the hope of future grace. Lines such as “Morning by morning new mercies I see” echo the lived experience of believers who wake each day dependent on God’s mercy.

Throughout the twentieth century, the hymn gained wide recognition, particularly through its frequent use at Moody Bible Institute gatherings and Billy Graham evangelistic crusades. Sung by believers from many denominations, it became a unifying expression of trust in God’s promises. Its use in funerals, thanksgiving services, and ordinary Sunday worship further cemented its place in the life of the church.

Today,this hymn remains a timeless reminder that God does not change. In a world of uncertainty and shifting circumstances, the hymn directs the believer back to the steady truth of Scripture. Chisholm’s simple testimony continues to speak because it reflects the experience of countless Christians who can say, with quiet confidence, that the Lord has been faithful, morning by morning, year after year.
