The amazing beginnings and growth of the Salvation Army are told through the stories of its founders, William and Catherine Booth. Even when attacked by angry mobs, the Booths and their growing army preached "the power of the blood of Christ and the fire of the Holy Spirit" to the destitute, desperate people unwelcome in the churches of nineteenth-century England. This highly readable biography will introduce new readers to the worldwide ministry of the Salvation Army and the pioneers who selflessly dedicated their lives to God's service.
