We had a bumper turn out last night - 13 of us - chiefly to three visitors. Typically, I had decided to tackle the incident at the end of Genesis 19 where Lot gets drunk and commits incest Anyway, I am committed to exposition andit was well worthwhile to look at these verses full of warnings and a hidden encouragement if you look (hint The Moabitess). We also had a good time of prayer - sometimes difficult with visitors but ot on this occasion.
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.
