Although he's better known for writing Amazing Grace, John Newton was also a faithful pastor who excelled at another kind of writing. Newton wrote countless numbers of letters, some to members of his congregation, some to friends, some to the newspapers as editorials, and some to other pastors. Newton's letters to one pastor in particular, John Ryland Jr., have been gathered and organized in a book called Wise Counsel. This fascinating and helpful work functions as a mix between history, biography, and devotional reading. For the next few weeks, I'd like to share excerpts from "Letter Five," a letter designed to encourage a discouraged Ryland.
