I was away from Childs Hill yesterday down at Pains Hill where I preach from time to time. It's always good to catch up with old friends there. Pains Hill Chapel is a lovely little chapel in the midst of the Surrey countryside. About twenty were there in the morning and a few less in the evening. I preached on 1 Kings 3:1-14 and 1 Thessalonians 1:4-10. The organist was away but we managed okay as she has recorded several of the hymns and it was possible to play these through the keyboard and we sang without too much difficulty eight hymns from a limited selection available. My assistant Andrew Lolley preached here and got on very well I understand.
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.
