Mathewson’s discussion of expository preaching as “more of a philosophy than a method” is quite good (pp. 21-22). He appropriately critiques pastors who preach all genres the same way. “The analytical outline approach presses the story into a mold that often works against it, especially when the outline points are alliterated or parallel,” (p. 26).
His review of the building blocks of a narrative plot are adequete (pp. 57-78). However, a pastor will only be a competent interpreter if he is already a reader. So, attempts to explain nuts and bolts about the narrative genre are of limited value. It would be akin to me, the investigations manager for a WA-state agency, trying to explain the basics of ERISA health benefit plans to laypeople and expecting them to do something meaningful with this information. Unless you are already “in the know,” such an explanation would be a waste of time. I fear it is here, too.
