Wales (playing appropriately in black) just about beat Japan today (33-30). it is difficult to see how Wales could have played so poorly. A win's a win but this was not much fun to watch. At least I'm not a South African. They're next.
Bonhoeffer uses a similar phrase 'worldly Christianity'. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.
