This volume contains 13 Discourses covering a great variety of theological subjects from the heart of a leading Southern Presbyterian Theologian from the 19th century. Thornwell lived from 1812-1862 and was an American Presbyterian preacher and religious writer. Joseph Addison Alexander, himself a wonderful example of pulpit eloquence, heard the sermon "The Sacrifice of Christ, the Type and Model of Missionary Effort" delivered, and pronounced it "as fine a specimen of Demosthenian eloquence as he had ever heard from the pulpit, and that it realized his idea of what preaching should be." J.W. Alexander once wrote the following of one of Thornwell"s sermons, "His sermon was a model of what is rare, viz.: burning hot argument, logic in ignition, and glowing more and more to the end." D. Martyn Lloyd-Jones said of him, "Thornwell was one of the greatest preachers that America has ever produced."
