I pray every day and I think everybody should. I don't think you can be up here and look out the window as I did the first day and look out at the Earth from this vantage point. We're not so high compared to people who went to the moon and back. But to look out at this kind of creation out here and not believe in God is, to me, impossible. It just strengthens my faith.
