‘All language about the future, as any economist or politician will tell you, is simply a set of signposts pointing into a fog. We see through a glass darkly, says St Paul as he peers towards what lies ahead. All our language about the future states of the world, and of ourselves, consists of pictures which may or may not correspond very well to the ultimate reality. But that doesn’t mean it’s anybody’s guess, or that every opinion is as good as every other one. And – supposing someone came forwards out of the fog to meet us? That, of course, is the central, though often ignored, Christian belief.’
Tom Wright, Surprised By Hope.
