I just came across an article by Batterson that relates imagination with preaching. He suggests that effective communication needs to be imaginative and “whole brain” (as opposed to left-brain only logical oratory).
There’s a great quote of Thomas Moore in the article: “It’s my conviction that slight shifts in imagination have more impact on living than major efforts at change.” (I’ve been asked to speak at a New Years Eve party/retreat about the difference between real change and empty promises – I’ll definitely be using that.)
Anyone who preaches would do well to check out the article.
While I’m making suggestions, Andy Stanley’s book, Communicating for a Change, is another helpful look at the art involved in the crafting and delivery of transformational preaching.
