Joan is walking slowly down the sidewalk when Power-walking God appears again. She's all energetic and huffy-puffy until Joan gives her a sharp glance. Then she slows down a bit, as Joan says, "I'm having second thoughts about you." Power-walking God explains, "It's called a crisis of faith. It's all right. It's not really faith if there's no crisis. Faith is an act of will, not a feeling." Joan wonders, "How do I know you're not the Devil? You asked me to do something, which I didn't do, and a good thing happened to Adam. Why would God want a good thing not to happen?" Power-walking God, who has the reassuring demeanour of a soccer mom, replies, "I understand you're confused. But there are no dilemmas without confusion, there's no free will without dilemmas, and there's no humanity without free will." Interesting, but it won't fit on a t-shirt very neatly now, will it? What good is philosophy that won't fit on a t-shirt? How will people know what you think? Joan sits down at the bus stop, saying in frustration, "I don't understand what you're saying. It's all just blah, blah, blah." Power-walking God blithely assures her: "It's not for now. It's for later." Hmm. Intriguing. Joan asks: "Are you really God?" She says, "You know I am." Joan laughs mirthlessly and says, "You know I don't know you are." But...if you know that she knows that you don't know...then you must believe she's God. Ah, Joan's thought of that: "Maybe you don't know because you aren't really God or maybe I'm crazy and I'm sitting here talking to thin air."
