William Gurnall

William Gurnall was a 17th-century English Puritan pastor and theologian best known for his substantial devotional work The Christian in Complete Armour. Writing in the context of post-Reformation England and the spiritual struggles of everyday believers, Gurnall distinguished himself by combining rigorous theological reflection with intensely practical pastoral application. His work is marked by an extended meditation on spiritual warfare, drawing from Ephesians 6, and is notable for its depth, vivid imagery, and sustained exhortation toward perseverance in holiness. Unlike some of his contemporaries, Gurnall’s legacy rests almost entirely on this single, expansive treatise, which has continued to be valued for its experiential divinity and insight into the inner life of the believer.
