A good day on the whole. We started on 1 Corinthians 15 in the morning and went over some of the basics of the faith. That is always good to do. In the evening I wanted to get back to Old Testament material and so preached on 2 Kings 5:1 and the beginning of the story of Naaman. I had reworked old material and so it did feel a little stale I'm afraid. It rained all day here and that kept one or two away I guess.
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.
