Reading this book is like listening in to an on-going conversation between two friends, who are committed to each other, their faith, and to their sense of wonder. Together they have traveled, shared many meals, and known the joy of a deep and abiding friendship. Through their dialogue, they raise the right questions and boldly share their answers. As a reader who becomes engaged in the conversation, you may find that not all their answers are complete, or satisfying, or even fully formed. The goal, however, is not to win you over to their perspective or theological stance, but to prod you into searching deeply within your own heart and mind as they invite you to join with them in the search for meaning, for perspective, and for assurances. They are courageous enough to ask the right questions and vulnerable enough to live with the tension of the unresolved answers.
