We had an encouraging get together in church this morning. David Green and Robert Strivens spoke on Bible background from the Old and New Testaments respectively. We must have had around 25 there - our own folk and visitors from other churches. We are very thankful to both speakers and all who came and all who helped organise.
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.
