I think of this book as a cross between a personal testimony and a study aid. Everything I put forward, whether historically or experimentally, has been hammered out on the anvil of personal experience and tested on the ground in community during the past thirty years. I go into the depth of things because it is my nature to do so and because I strongly feel that such a treatment of the topic is of contemporary relevance. There are more than enough bland books about Religion and God and Faith and all that on the market to do us for the next century.
