I had a nice day off this week. I managed to get my 10,000 steps in again and I finished Gimson's book on the presidents and read most of Dale Ralph Davis's latest book on the psalms, which lives up well to its usual standards. I also listened to Louis Theroux interviewing KSI, which was interesting, enlightening and in the end quite disturbing in some ways. (KSI is a YouTuber with a massive audience mostly of young people). Let me repeat that I try to report on the day off because I think it might encourage others in ministry to try and keep some pattern in their lives. Therefore, I should add that I began the day making a to do list and some of those things just had to be done on that day so I did them.
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 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.
