A bank holiday weekend means numbers are likely to fluctuate and they certainly did. There were at least ten missing, half of them down in Cornwall on various trips. On the other hand we had relatives staying, an old friend visiting, a lovely young Nigerian family staying in the hotel round the corner found us and in the evening we had several men in London for NYL's Christian Answer weekend. One odd thing was that although there was only one child when I did my children's slot on the slough of despond, there were five by the time Sunday School came round in the sermon period. I preached a one off in the morning on Isaiah 60:1. Such a great text. In the evening we looked again at Matthew 8 and at the storm on the lake, one of the great New testament passages.
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.
