Believing in the Face of Doubt

This is a most unlikely sentiment from a Fabian like Edith Nesbit, but it's remarkably apt (and I never noticed it when I first read The Railway Children).

Don't you think it's rather nice to think that we're in a book that God's writing? If I were writing the book, I might make mistakes. But God knows how to make the story end just right - in the way that's best for us." "Do you really believe that Mother?" Peter asked quietly. "Yes," she said, "I do believe it - almost always - except when I'm so sad that I can't believe anything. But even when I can't believe it, I know it's true - and I try to believe. You don't know how I try, Peter."
