" Preachers, therefore, must avoid vacuousness in their preaching, and they must avoid heartless intellectualism. The object of all true preaching, after all, is the heart, and preaching has failed “unless it makes men tremble, makes them sad, and then anon brings them to Christ, and causes them to rejoice. Sermons are to be heard in thousands, and yet how little comes of them all, because the heart is not aimed at, or else the archers miss the mark. "
