This is a practical and personal guide to spiritual growth. Though there are lots of books on spiritual growth and Christian living out there, a lot of them fail to address the issue of emotional baggage. That's what makes this book superior in many ways. It deals with what you bring from your upbringing into your faith, and it realistically portrays suffering as something that should not be ignored, but rather compel us to wonder and grow.
Beware, it's not a very theological book. Peter Scazzero gives theological basis for some of his ideas elsewhere, and I recommend people check out some of his sermons and seminars (a lot of them can be found online). Yet, I don't consider his claims that controversial or in need of great justification, and I doubt many people will object to this book for theological reasons. Maybe for personal ones.
