I started writing the book without realizing I was writing a book. That sounds stupid, but it's true. I'd been trying and failing to make a different manuscript work, and I thought I was just taking a break by writing some short stories. I'm not a very good short story writer - the amazing compression that is required for short stories doesn't come easily to me. But anyway, I thought I'd try to write some short stories. And a structure took shape - I stumbled upon it.

I think of my success as a kind of fluke. How else could I possibly think of it? And although it's a banal thing to say, I wrote my book because I was writing my book. At first I didn't know I was writing it, and one of the amazing things that happened as I was putting sentences down on paper is that some of the things that are most sacred and important to me rose to the surface of the prose.

At some point I just acknowledged, at least to myself, that I had a great deal of respect for people of faith. Faith is a strange and wonderful thing. You come up to a kind of wall of unknowing and instead of turning back in despair you leap over it into something else. The Church isn't why I'm a writer, but it's probably a part of it.

I think that if you just write your characters you end up with something that people can access.

A belief in God may not be fully within me anymore, but there's still a belief in belief. The high drama and power of the Church has stayed with me. As a child in church, I saw grown men at the altar crying out for God's mercy. And the idea of someone doing that has become a joke in the popular culture, but when you are there and you see it, you experience - for a moment - an incredibly raw, honest, strange insight into what it means to be a human being. Those experiences don't leave you. Whatever you think of them, they are powerful experiences.

One of the things that writers worry about is finding a voice. I don't think it's a thing that you find so much as it is something that comes to you, or that presents itself.
