As a mere photo, this is useless. What I remember and what I cannot convey to you is the smell of camphorated ointment. For years we had a little grey cardbard box of it with a hand written label in the bathroom. I was no asthmatic but if I did go to bed with a chesty cold my dad would make sure I had a liberal dos of camphorated ointment on my chest. How well it worked I don't know but the smell was pleasant enough and the fact that he believed so much in it was enough for me. Aaah, I miss my dad.
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.
