Brother and Sister Bear's friend Ferdy Factual loves science. Brother and Sister like science too. They like digging for fossils, examining the moon through their telescope, and peering at tiny things under a microscope. But Ferdy tells Brother and Sister that he doesn't believe God created the world. In fact, he doesn't believe in God at all. This is a new idea for Brother and Sister. Together with Mama and Papa, they visit Preacher Brown to find out what it means to have faith and learn a lesson from Daniel who had faith in a den of lions.
