One pious answer places God in heaven. Another in cathedrals. Another in his sanctuary. Another everywhere, in nature. Yet another, alas, nowhere. The question is not idle. Does God dwell near us, or far from us? Does he dwell in one place, or is he willing to move? Can his dwelling be visited, and if so, what are the conditions of access? Or is it a place completely closed to all human visitation? Answering these questions is the entire purpose of this book.
