This book is very informative. If you feel you are called to the "ministry of intercession" then this does help you to understand the different types of intercessors that are in the body of Christ. And it is an encouragement that we are all called to be intercessors but we are not all the same. But we are equally valualble in the body of Christ. and we each have a part. Great addition to your library and a good one to pass along to your friends.
