Everything is behind this week. We did meet last Wednesday and looked at the next of the Psalms of Ascents - Psalm 121. It is a famous psalm but there are some difficulties with it, beginning with what looking to the hills is all about. I also wanted to say there the reference to the sun and moon was a merism, that is to say two opposites are mentioned to cover the range (as in the opening verse which refers to heaven and earth but includes everything God made). Could I think of the word merism or find it through google, however? No way. Anyway we got through the psalm and made some useful points I hope about God and his care for us . We also had a good time of prayer.
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.
