I preached another one off last Lord's Day morning - on Hebrews 10:23-25. Despite my pleas there seemed to be no more present in the evening nor did most seem less lacadaisical about time. There are many away at the moment so things are a little unpredictable. In the evening (when we carried on in Matthew 9) an Israeli man was there at the beginning. He didn't stick around. I also noticed a local Swedish man who likes to talk present at one point but soon gone. When the service was over an East European couple put their head around the door (he was Croatian, she from Kyrghyzstan). At least three friends (Ghanaian and Iranian) who arrived just after the sermon in the morning did stay.
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.
