This is a piece on C.S. Lewis’s favorite books, which talks especially about the odd book out, the only one that’s not Christian: Virgil’s Aeneid.
My favorite line, I think, is Lewis’ writing to Dorothy Sayers that “The effect is one of the immense costliness of a vocation combined with a complete conviction that it is worth it.”
In other words, calling is for grownups, and hearing a calling involves learning what it means to be a grownup instead of an overgrown adolescent. (I’m still learning.)
