We went back to our Bible study and prayer format this week. We took up where we had left off in Genesis 18 and just looked at the opening verses and God as the God of beginnings (the birth of Isaac is announced) and endings (the end of Sodom is intimated). It was good brief session followed by items for prayer and prayer itself, all of us again praying (about nine we were I think). Some were missing.
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.
