When I was doing reading skills for exegesis at WEST (my theological college) this was core text and very interesting and useful it proved to be. This really is an incredibly well thought out book that provides you with most of the things you need to understand if you are going to preach a passage of the Bible. All the key ingredients are here, putting the passage in context, understanding what kind of literature it is. How to approach the exegesis of the passage (a fancy theological term for understanding its construction and what it's all about). Understanding in its context and then bridging the context by applying its teaching and principles to the present day. The book is very detailed looking at several kinds of biblical literature and giving the reader an understanding of how to approach and then preach each one. If you want to get two books on preaching then get this one and Stuart Olyott's 'Preaching pure and simple' and you should find that they help your preaching alot!
