1843–1919
A pioneering preacher and prolific devotional writer, this Canadian-born pastor helped spark a worldwide missionary movement. His books blend earnest faith, practical spiritual counsel, and a strong sense of Christ-centered mission.

by A. B. (Albert B.) Simpson
Born in Prince Edward Island in 1843, A. B. Simpson was a Canadian preacher, theologian, and author who became best known as the founder of the Christian and Missionary Alliance. After serving as a Presbyterian minister, he moved into independent evangelistic and missionary work, especially in New York City, where his ministry reached both urban crowds and people on the margins.
Simpson wrote widely on Christian life, mission, healing, and deeper spiritual devotion, and he also composed hymns. His preaching and writing helped shape a movement with a strong emphasis on global evangelism and practical faith, and his influence continued long after his death in 1919.
Readers often come to Simpson for his warm, urgent style: direct, devotional, and deeply focused on living out the Christian life rather than merely discussing it.
