I have done much reporting in what might be termed the religious field. I have interviewed dozens of people-maybe hundreds-asking questions about their beliefs. Some impressed me more than others, but it is impossible to avoid the conclusion that the gift of faith (and I think it is a gift) is the most valuable one of all. People who have it are stronger-and kinder-and more unselfish-and happier. It's as simple (and as mysterious) as that.
