John Knox, Professor of Sacred Literature at the Union Theological Seminary, New York, is himself an eminent preacher as well as teacher of preachers. In this small book, written for those who are called to preach, is to be found distilled wisdom of a high order. It is Biblical preaching that is needed, he writes, rooted and grounded in a sure knowledge of the Bible and the historic meaning of the text, but the preacher must go on to treat the Biblical events as events in our own history. Christ must be central to preaching, as He is central to the Bible, but the Event is in a real sense constantly recurring, and the modern hearer should be hearing the texts as if spoken directly to him. Dr. Knox sees the preacher also as teacher, but one who conveys the meaning of his sermon more by what he is than by what he says, though his words must be spoken with care, after the preparation of loving labor. Preaching is also worship, and a sacrament, demanding the best a man can give to this high calling. Every Protestant minister will read this to his great profit, if he is concerned to keep his preaching alive and relevant to our times.
