A distinguished historical study of the founder of the Methodist movement. The author presents a portrait of John Wesley not only as an evangelist but also as a Church of England (Anglican) figure who sought to renew the church from within. The book depicts the sluggish social and religious situation in 18th-century England and how Wesley brought about a 'revival' through field preaching and the organization of small fellowships. It examines Wesley's experience of spiritual renewal, particularly the events at Aldersgate, where he felt an inner conviction of salvation that transformed his approach to ministry. The author highlights Wesley's emphasis on practical theology, where faith must be embodied in daily life (holiness of life) and love for others. The book frequently highlights Wesley's extraordinary dedication, tenacity, and self-discipline amidst the persecution and hardships he faced during his ministry. Overall, the book provides a balanced picture of John Wesley's personal life, theology, and historical impact on the Christian world.
