"Writing about Christian life...is like trying to paint a picture of a bird in flight. The very nature of a subject in which everything is always in motion and the context is constantly changing -- rhythms of wings, sun-tinted feathers, drift of clouds (and much more) -- precludes precision. Which is why definitions and explanations for the most part miss the very thing that we are interested in. Stories and metaphors, poetry and prayer, and leisurely conversation are more congenial to the subject, a conversation that necessarily also includes the Other."
