Chaim Potok wrote in 'The Book of Lights' about two American rabbis, both army chaplains, in Japan during the Korean War. They passed a Japanese man praying devoutly beside the roadside shrine. One rabbi said to the other, 'Do you think our God is listening to this man?' He went on, 'If our God is not listening, what do we mean when we say "God"? And if he is listening, what do we mean when we say "we"?'
