I seem to be rather our of sync with these midweek reports. This one is late and I didn't do one last week because we had only a prayer meeting as part of our week of prayer meetings. I appear to have given nor report the week before either (September 23). That was on the cross - a tree of death and of life. Anyway I went on this week looking at the vine, considering Isaiah 5, Ezekiel 17, Psalm 80, Matthew 21 and especially John 15. It was more interactive and more of a Bible study this time round than usual. We had a good turn out and a good time of prayer. What an oasis these midweek meetings can be.
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.
