The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culturehere. 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.
Amazing win for Wales in first game of Six Nations 2019
Somehow Wales have won the first game in France against a French side that was 16-0 up at the end of the first half against an error prone Wales team.
We ended up winning 19-24 as Frane also fell into errors.
