I always love how the semitic religions claim to know so much about God, until you ask them to demonstrate Him, then suddenly His ways are mysterious, and "Who are you to question Him?" It's the age old trick of trying to have your cake and eat it, too.
But really, I don't mind. I'm a woman who believes in the "give 'em enough rope" method of argument. But it did get me to thinking, given the argument for the existence of God posted in the other thread, challenging the atheist to show how the universe came into being without a creator, and I came to a conclusion. What's sauce for the goose is sauce for the gander. The next time a theist challenges you to explain the origin of the universe, you should assume the appropriately sanctimonious tone and reply, "The universe's ways are mysterious. Who are you to question Its ways?"
