Hi, Sam (and hello to the family)!  Thanks for the article.  Responding to the "information is insufficient for change" thesis, and also to the direction of comments relative to sermonizing, I have to say that as a longtime member of a small SDA church that has experienced a multitude of pastors, we have had a few who knew how to preach effective sermons but far too many who either had no clue or were too lazy to put forth the effort required to prepare and present an effective one.

You mentioned Joseph, who was changed by a traumatic experience.  Words are often less transformational than experience.  The power of narrative preaching is that by embedding the listener in a story, they are themselves transported into the setting, and then transformed by the experience.  This is very different than "evangelistic"/Bible study exercises in conveying information.  It is truly life transformational--shifting people to a new paradigm.  I highly recommend Milton Crum's Manual on Preaching.
