The author offers a comprehensive chronological biography of John Wesley, assembling extensive original manuscripts, letters, periodicals, and scarce publications to trace his life, ministry, and role in the emergence and spread of Methodism. The narrative emphasizes factual detail over speculative interpretation, documenting organizational developments, affiliated societies and denominations, missionary and social initiatives, and controversies surrounding earlier biographies. The work synthesizes newly uncovered sources with published material, supplies a portrait and indexes, and aims to present an honest, densely documented account that lets readers draw their own conclusions about Wesley’s aims and influence.
