Jeremiah: Interpretation: A Bible Commentary for Teaching and Preaching

My husband and I are team-leading a Bible study on Jeremiah. The breath of fresh air is this commentary, which is well written, interesting, and doesn't appear to preach a particular bias - just presents information about the book of Jeremiah. However, a warning on the class book and the downloadable leaders manual! The leaders manual is juvenile. Our class of 35-to-50 year olds laughed at the idea of "arts and crafts." We haven't done any of that. They would be appropriate for kindgergarten-to-first graders, no kidding. We are not particularly liking the IBS lesson book, either. The lessons are far too long for an hour class - actually too long for a 2-hour class! In addition, the authors appear to have such an extremely liberal focus that they will spend an entire (2+ hour) lesson preaching their cause . . . while completely ignoring what's actually in Jeremiah. We have had to create at least one lesson from scratch, as a result. Some of the chapters are pretty good, albeit too long, but our class is interested in studying Jeremiah, not one of the authors political views.
