Pros: ''What comes into our minds when we think about God is the most important thing about us.'' (A.W. Tozer) This study series, while not inexpensive, has been the most life-transforming resource I have encountered in many years. Week after week you are brought back to ''Who is your God?'', until it begins to effect real life change. The humility and winsome lives of the presenters is a huge endorsement for their message. But don't take my word for it -- visit the site and watch the introductory videos. Start this with a small group; you won't regret it.
Cons: We found it difficult to adequately meditate on the materials in the space of a single week and ended up stretching the lessons over two weeks -- but we were all delighted to get to spend more time on the study!
