I post this Beatles video chiefly to salute my good friend and fellow elder Robert Strivens who receives his doctorate this week. I am also planning to be listening to another Dr Robert (Letham) this week at the John Owen Centre, who I hope will be helping me to understand the Trinity. Typical of sixties rock I guess the original song is all about drugs really but it is a very pleasant pop song, nevertheless.
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.
