Somehow I forgot to do a midweek meeting report last week. Anyway, we did meet and we looked at that wonderful verse Romasn 8:28 and we spent time in prayer too. We were not a great number as some are still away.
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.
