John Wesley was an 18th-century preacher, theologian, and cleric who helped found the Methodist movement with his brother, Charles. Arguably one of the most important Christian voices of his day, Wesley wrote in his journal on a daily basis, capturing his views, thoughts, feelings, and prayers on paper to share with the world. The journal contains 50 years' worth of this great man's reflections and experiences and is widely considered one of the great spiritual classics.
