I'm not one to normally quote Heschel, but Richard John Neuhaus quotes this great story from Abraham Joshua Heschel:
Heschel had a great appreciation of the embodiment of truth in tradition. He was fond of telling the story of a woman who approached him in the synagogue, complaining that the service did not say what she wanted to say. "Madam," he responded, "you have it precisely backwards. The idea is not for the service to say what you want to say but for you to want to say what the service says."
