I'm sure they've mentioned them before but there seems to be a lot on the weather news this winter about the closing of snow gates. I'm niot entirely sure what these are though I suppose thye are designed to keep people from putting temselves in danger. The above picture is on a B road somehwere north of the border.
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.
