The author engages in an experiment of trying to be purely objective about the Christian faith, which he has embraced for over thirty years. Halfway through the book his experiment leads him to an unforeseen realization. For the remainder of the book, he then engages in an experiment of trying to be purely persuasive.
Two “ground rules” guided the author throughout this project. First, the writing was to be conducted in a series of one-hour sessions, as measured by a timer. Second, each session had to take up and carry on from whatever point the previous session had reached. From the onset, he did not know where this project would take him; but all along, he felt that was part of the adventure of it.
