The value of a Francis of Assisi or a John Wesley is not exhausted by their heavenly citizenship. We want to know how they behaved on earth--how they controlled their human passions and made themselves the instruments of God. That aspect gives abiding interest in this book. Dr. Rattenbury has certainly succeeded in treating the story of the Wesleys in a style that will appeal not only to Methodists but to anyone who understands something of the enduring significance of the Evangelical Revival.
