Just nine of us last night as we began on that difficult but challenging chapter Leviticus 19. I think it i is easier to preach then to explain. That is to say it is easier to apply the various verses than itito explain why you are applying them in that particular way. Most of us prayed in the preyaer time. There is always plenty to pray about.
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.
