I was reading an article on preaching the Apocalypse and the author opened with this statement,  "Evangelical preaching from the Apocalypse gyrates wildly as it caroms off walls of neglect only to settle into theological opium fields where enthusiastic illusions inhaled from the fertile poppies of human imagination are passed on to bewildered congregants as insights into the minute details of the last days."

Did you get that? I love metaphors. But the metaphors are so copious I felt like I was reading metaphors of a metaphor. In every form of communication it's good to use colorful, strong words that you can smell and taste, see and hear, but you know you've stepped over the limit when the reader is spending more time trying to interpret all seven metaphors (yes, he used seven) than thinking about the point you were making.
