To step through the looking glass, to pass through the wardrobe into Narnia, to attend the birthday party of Bilbo Baggins is to reenter the world of childhood more fully than is possible any other way. It is not just a matter of being reminded how strange and new and promising everything was back then, but of experiencing it all over again.
Regardless of how many times you have read the books you loved as a child, the elements of surprise and suspense are always present, so that right up to the last minute you can believe that Scrooge will go on being miserly in spite of everything and that Dorothy may never find her way home.
To us, as to the child, the happy ending always comes as an unexpected gift from on high. It is the deepest truth that children’s books have to tell. Possibly it is the deepest truth there is. – Frederick Buechner
