It was unseasonably cold yesterday (I'm dreaming of a white Easter!) and that probably affected attendance. There were a few visitors, however, from Holland and Romania and less far a field. We carried on with 1 Corinthians and preaching the gospel, reaching 2:5 at last, in the morning and in Numbers (28) in the evening. My main points in the evening were about being thankful that we don't need to knlow the details of that chapter well today and how it teaches us about Christ's sacrifice and our own since that time.
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.
