"I don't believe in God, but I miss him."

This is the opening line from a book titled Nothing to Be Afraid Of by the award-winning British writer, Julian Barnes. Barnes, who describes himself as an agnostic, writes, "I was never baptized, never sent to Sunday school. I have never been to a normal church service in my life." And yet this agnostic intellectual still feels haunted by the beauty of Christian art and music and by what he calls the "wake up call to morality."
