This book is definitely an amazing tool for emotional healing. Anyone who has experienced anxiety, depression, stress, or any other sort of emotional trauma should know about this book and these techniques. Christians especially need to know about Emotional Freedom Techniques, because for thousands of years, the Christian church has (incorrectly) viewed the body and soul/spirit to be separate, if not at odds. In this book, the body/soul dichotomy is challenged in a biblical manner.
The techniques taught in this book use the functions of the body that God already placed inside of us to help relieve and heal trauma and stress-related problems. The steps taught in this book are clearly explained. The science behind the techniques is explained, as well as the spiritual aspects. There is not "blind faith" or mysticism involved. When you begin practicing the techniques, you know what you are doing and why it should work.
I personally think that every Christian should read this book. Many Christians don't know much about emotional and mental frailties, so they assume that such problems are a "faith issue," and that simply isn't so. Christians need to educate themselves about the body and mind, since both of them were given to us by God, and he can bring about healing through all of the 3 parts of our being.
