We had a good time of prayer the other night - probably because In allowed plenty of time and there was plenty to pray for. We were also a good number. We looked at the last of the solas or alones of the Reformation - Soli Deo Gloria. We went to Romans 11, 2 Timothy 1 and 6 and 1 Corinthuans 10:3. What a wonderful theme.
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.
