Nine of us gathered last Wednesday for the midweek meeting. We carried on with the next bit in Haggai (1:5-11). That was nice and brief and so we had plenty of time for gathering prayer material (always plenty of that around) and then praying for a good little while. Six of us took turns to lead in prayer. I wish we'd all prayed.
The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. 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.
