I found this piece of gold on Byron's blog. Enjoy:
“How can we make clear the victory of Christ? In this way: when speaking of sin, demons, darkness, by not speaking of them in too tragic a manner—like the German theologians, all so serious! The further north you go in Germany, the more they are concerned with the realm of darkness. And if you move to the Scandinavian countries, all is darkness: God against Satan, and vice versa! ... It is not wise to be too serious.”
—Karl Barth’s Table Talk, ed. John D. Godsey (Edinburgh: 1963), pp. 16-17.
