A dissolute and wasted life was transformed into one of the most effective preachers in the north of England in the eighteenth century. When William Grimshaw arrived at Haworth as the new parish minister, only a handful attended the church; within a few years over a thousand could be found at the service of communion. John Wesley once hoped that he would succeed him as leader of the Methodists, but Grimshaw's unsparing work for the gospel meant that he died nearly thirty years before Wesley! This is the incredible story of an eccentric enthusiast for the Christian message.
