We were not so many on Wednesday as several are away at present. We were still nine, however, and we pressed on with the third of these solas grace alone. It is a wonderful theme. I chiefly focused on Ephesians 2:8-10, verses that are always good to go back to. People were keen to pray. I think all nine of us prayed at least once. There's no better place to be than with God's people.
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.
