There is an interesting Bible verse I had in mind today: "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."
It reminded me of the movie No Country For Old Men in which both the protagonist and antagonist are treated with incredulity by various people wherever they go. It's the same kind of phenomenon. No one can discern their motives. This is contrasted with how the Sheriff treats his assistant, easily telling that he doesn't know what he is talking about. So it is.
