The only chapter in the book that didn't require you to have read and accepted the bible from cover to cover is the first chapter (and I happen to just patently disagree with his view in that chapter). The rest is C.S. Lewis's views on many holdings of the christian faith, much of which are presented verbatim in his words as: "these are merely the facts of christianity". If you're skeptical at all about the authenticity of the bible beyond jesus being a moral teacher, 90% of this book will be disappointing as it just explains what a "true" christian ought to be like (according to the author). It talks nothing about the convention of jesus being a man and a savior and how his life validates the premise of christianity (and, by association, a departure from judaism).
