We ended up starting on two new series on Sunday. Having finished my morning series on John 3:1-21, I decided to make a start on 2 Peter, beginning with 1:1-4. I think I amde heavy weather of it for some reason. In the evening I thought we were due for a break from Numbers adn so started another sereis - this one on Habakkuk. We also met for communion before the evening meeting. Numbers attending were okay. It was particularly good to have some back who have not been in a while adn two visitors who I hope we will see again.
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.
