Do check out this post by Dr. David Allen entitled, "An Altar Inscribed 'To the Unknown Preaching Method.'” The post begins with this great paragraph.
On any given Sunday in today’s preaching pantheon, one can observe a diverse group of devotees, some paying homage to the chapel of “creativity,” others sitting at the feet of the “culturally relevant.” Some are transfixed at the nave marked “narrative,” while others have their hearts strangely warmed at the chasse of “pop-psychology.” There is never a shortage of worshippers at the “new homiletic” altar, and the “topical” shrine always receives its share of Sunday patrons. Fearful that some as of yet undiscovered homiletical “method” might be missed, the gatekeepers of the pantheon have installed an altar inscribed “to the unknown preaching method.” It is that method which I declare unto you. Actually, the method itself is not “unknown” at all, and like the true church on earth, it has always had its practitioners in every era of church history. In fact, it is the oldest method in the preaching pantheon, having been used by the earliest preachers as far back as the apostolic era of the church. It is called “expository preaching.”
