These are the sermons John Wesley placed at the foundation of the Methodist movement — the doctrinal standards by which his preachers and people were to be judged. Across them, Wesley unfolds the gospel he had recovered at Aldersgate: salvation by faith, the witness of the Spirit, holiness of heart and life, Christian perfection. Read straight through, they are nothing less than a complete theology of the Christian life, in the warm pastoral voice of the man who walked the lanes of England preaching them.
