Some preaching is like the winter sun: it brightly illuminates the mind but leaves the heart cold. Other sermons are like cotton candy: they taste sweet but contain no substantial nutrients. Biblical sermons, however, need both heat and substance--a conviction at the core of the great Reformed tradition of experiential preaching. Reformed experiential preaching not only informs minds, but also engages hearts and transforms the conduct of hearers. This robust treatment of Reformed experiential preaching by Joel Beeke--a pastor and professor of preaching with over 4 decades of experience--explores the heart of Reformed preaching, examining sermons by preachers from the Reformation and bridging the historical gap by showing pastors what the preaching of this life-transforming truth looks like today.
