After 20 years of teaching the book of Jeremiah, Mr. Carroll has apparently come to the conclusion that neither he, nor anyone else, has any real clue as what it's about, or what any of it really means. He is very pessimistic about our ability to understand Jeremiah. After reading his book, I wondered why he even bothered to write it, other than to tell non-scholars that they're wasting their time. That being said, there are a few useful insights and it can help prevent a reader from being too naive about his grasp of the message.
