I'd thought numbers might be own a bit last night but we weren't too bad even with four or so missing. Two sort of visitors helped. We looked at the final verses in Philippians, which we started back at the end of 2014. It was the twenty fourth in the series. I was not long on these closing verses (4:20-24). It's always good to end with grace. There seemed to be loads of things to pray about including a number prospective new attendees. We'll see.
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.
