F.F. Bosworth (1877–1958) was an American evangelist, author, and faith healer known for his influential ministry during the early Pentecostal and healing revivals. He gained prominence through his preaching and healing campaigns across the United States and internationally. Bosworth is best known for his book Christ the Healer, a foundational text promoting divine healing based on biblical principles. Though associated with Pentecostalism, he later distanced himself from certain charismatic expressions. He emphasized faith, the power of God’s Word, and Christ’s role as a healer. His teachings significantly impacted the healing revival movements and laid the groundwork for future evangelists like Oral Roberts.
