Chapter 3 is titled "You've Gotta Show Up" that basically sums it up. God invites us to change, but He won't change us unless we ask. We have to choose to ask Him, to show up, and if we can't do that, we should pray to want to show up.
The rest of the chapter describes the meetings that are a part of the FirstPlace 4 Health program, which is a faith-based weight loss program. It looks a lot like a Weight Watcher meeting with Bible study and prayer added.
