Numbers were rather down yesterday as it is the beginning of half term week here. We pressed on with 1 Corinthians, however, beginning on 1 Corinthians 14, which is difficult but full of good practical advice with regard to worship. In the evening, when we were down to about 15, I began a short series on the parable of the sower focusing on the seed on the path that gets eaten up by the birds.
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.
