My Monday entry is very brief. I say something typically banal about my daily reading (Matthew 21-12-20), bemoan my failure to witness though I mention that my sister is reading her Bible still (I guess she was converted somewhere around this period) and bewail what I call the "many sinful vices creeping upon me lately". The only example of this that I give is (shock, horror) BORROWING! I tend not to name things that really did trouble me as a teenager but as someone who had been brought up not to borrow things I can see how this would have been on my conscience. I spent the evening, unusually, doing homework. I was also listening to Focus, of course. Probably on the old radiogram. I don't think I got my Philips 303 until the following May.
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.
