We were very few last night but it was good to meet and to look at the opening verses of Deuteronomy 31. This includes the verse about God not leaving or forsaking his people. I drew on other similar verses to flesh out the idea. It was meant to encourage and I hope it did. We didn't pray for long being not many but we sought the face of the Lord.
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.
