I take the kids to church and Sunday school. They love it. I really think it's important for a child to feel that there are things that are bigger than your life out there.
Teaching is more difficult than learning because what teaching calls for is this: to let learn. The real teacher, in fact, lets nothing else be learned than learning. His conduct, therefore, often produces the impression that we properly learn nothing from him, if by "learning" we now suddenly understand merely the procurement of useful information.
