The proposal of this book is to guide the reader to the contrastive ministries of the two most dominant preachers of the eighteen-century evangelical revival. In a wonderful comparative approach the author draws John Wesley and George Whitefield's portraits and explores their life and practice, as well as their relationship. Committed to the principle that the 'whole world was their parish', Wesley and Whitefield manifested their singular desire to be men of one book through preaching ministries that were equally committed to the spread of the gospel throughout the transatlantic world.
