Introducing the Edward Carnell Library (Nine Titles Listed Inside) Rather than mounting a rational proof for God's existence, the author advocates here a "spiritual approach to God." This calls for an exercise not only of one's rational faculties, but also of the spiritual. The four parts of this book, originally published in 1957, treat the development and application of "knowledge by moral acceptance," the process of becoming acquainted with the person of God, and concluding inferences and problems.
