I would say this book is about cheer leading. It talks about tapping into that divine power of God through prayer and lots of it. While we all could probably use more prayer time, I think we need to guard against praying superficially and Batterson's "any place any time" recommendations seem shallow. I would say the book is not very deep, that is why I say cheer leading, if you need someone to remind you to pray daily, this may help but there are other ways as well. Find what works for you.
I am just blown away by this book...From day 1 it is like it was written just for me!!! I am applying it to my life daily and plan to continue until the day I meet Jesus face to face...Looking forward to getting The Circle Maker!!!
