John Newton is famous for his legendary hymn "Amazing Grace." Many have celebrated his dramatic conversion from a life in the slave trade to his eventual work to end it. But often overlooked are Newton's forty years as a pastor ministering to parishioners and friends unsettled by the trials, doubts, and fears of life.

Newton is perhaps the greatest pastoral letter writer in the history of the church. He took up his pen day after day to help others fix their eyes on Christ, which, he writes, is the underlying battle of the Christian life. Through a careful study of scores of letters, Tony Reinke brings together Newton's brilliant vision of the Christian life in one accessible place.
