Ernest Orlando Sellers (1869–1952) was an American hymn writer and composer whose work contributed to early twentieth-century Protestant hymnody. Although detailed biographical records about his life are limited, he is remembered primarily through his numerous hymn texts and adaptations, which reflect a strong devotional and evangelical character.

Sellers wrote or contributed to at least seventeen known hymn texts, many of which emphasize personal faith, Christian living, and the believer’s relationship with Christ. His hymns often draw directly from Scripture, both in theme and language, showing a clear intention to make biblical truths accessible and memorable for congregational singing. Some of his works also appear in multiple languages, including German and Spanish, indicating a wider reach beyond English-speaking congregations.

Among his better-known contributions are hymns such as “Would men know you've been with Jesus,” “Through toil and sorrow, through pain and strife,” and adaptations like “Thy Word is a lamp to my feet, a light to my path alway,” based on Psalm 119. These texts highlight themes of discipleship, perseverance, and the guiding power of God’s Word. He also worked as an adapter of existing hymn texts, helping to reshape and preserve them for continued use in worship.

Though not as widely documented as some of his contemporaries, Ernest O. Sellers played a meaningful role in shaping devotional hymn singing in his era. His legacy endures through the continued use of his hymns in various Christian traditions, especially where simple, Scripture-centered expressions of faith are valued.
