“It took me a while to realize that these stories, while often used with children, are not at all children's stories. I think the devil has tricked us into thinking so much of biblical theology is a story fit for kids. How did we come to think the story of Noah's ark is appropriate for children? Can you imagine a children's book about Noah's ark complete with paintings of people gasping in gallons of water, mothers grasping their children while their bodies go flying down white-rapid rivers, the children's tiny heads being bashed against rocks or hung up in fallen trees? I don't think a children's book like that would sell many copies.”

Context: Parents rarely let go of their children, so children let go of them. They move on. They move away. The moments that used to define them - a mother's approval, a father's nod - are covered by moments of their own accomplishments. It is not until much later, as the skin sags and the heart weakens, that children understand; their stories, and all their accomplishments, sit atop the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives.

Their mother does not put "Let's pretend" into the child's mouth; she finds it there. Without it there is no play. But the pretending is always drama and never deception or self-deception.</p>
