This is an easy read on face value; A journey through the author's struggle with the profound difference between religiosity, and spirituality. (Or in a less mystic-sounding sense, ritual and relationship.) Yet, this isn't the kind of book that one can just devour. Well, I suppose you can, but it's not really structured like a novel. It's more of a semi-chronological series of simply written essays strung together in an affable, conversational voice. 
 It is essentially one man's often humorous personal journey in how he and his relationship with God has developed and changed, and how he has continued to change through it. I found I could only go a chapter at a time or so before I had to put it down and think about it. That, in my mind, is the mark of something good. In confronting himself, he caused me to take a good hard second look at myself. Not something I'm challenged to do often enough, frankly. 
 While I consider the book to be totally a worthwhile read, I think it's worth noting that it at times feels like an ongoing apology on behalf of 'religious' Christianity. The author grew up in a stiflingly legalistic setting that strangled his faith while pushing 'religion' on him and everyone else. It's understandable that he would eventually run screaming in the opposite direction. And while he doesn't project one iota of hatred or hostility toward any part of humanity, it becomes clear as you go that he still harbors certain misgivings toward his perception of 'Republicans'. That alone may be a selling point for some people. If it is, you'll probably like this book. If it's not, read the book anyway. There are still plenty of valid points and thought-provoking concepts to chew on in spite of the bias. It's a good 'check yourself' book for Christians, but not something I would consider an Evangelizing tool due to the subtle but pervasive threads of non-confrontational resentment. 
 I don't know if anyone else felt this way, but to me the book seemed somehow incomplete. And not just in a 'life is a continuous journey' sort of way. I felt like it needed one more chapter to tie everything up more neatly, or perhaps expand more on his very briefly mentioned points about the need for Christians to love, but not be wishy-washy. I don't think he meant to sound like he considered the bible to be irrelevant, but his position on it's value also came across a tad confusing. 
 Above all I found tremendous value in Miller's grasp on how badly the point of Christianity has been lost by some, along with the love of Christ. Don Miller is all about emphasizing the love of Christ, I'll certainly credit him that.
