The book I have describes "it" as the gift of Grace. Grace is a bit different than faith, I think. The whole 1st chapter is devoted to it, so there really isn't any one paragraph I can quote that will make sense out of it. But I suppose from the perspective of a person of faith, it would make very good sense. I would especially recommend this book to a person of faith who is struggling with worldly crises, tragedies, etc.
I believe Morning Glory has started a thread about Grace; I'll find it and post the link.
