Seven of us gathered last Wednesday as we tackled the next bit in the life of Abraham - the detour into Egypt. Lots of help from Dale Ralph Davis again but trying not to rely too much on him in the wrong way. Good prayer time too, although I could have given us longer.
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.
