Slogging along in the paths of righteousness by Dale Ralph Davis is Davis's apparently unplanned follow up to The Way of the Righteous in the Muck of Life. The first book covers Psalms 1-12 and the second Psalms 13-24. Both books give around 10-12 pages to each Psalm, beginning with Davis's own careful translation and characterised by his usual mix of gentle scholarship, playful language, brilliant illustrations, judicious quotations and helpful applications. I am far from being alone in recognising what a great gift Dr Davis is to God's people. Another 10 books like this would be most welcome. The only problem I can see is with titles and special effects for the covers (for the first we had slightly raised mud splashes which I did try to rub off and this second has colour in a black and white photo). How about Trudging the Lord's ways through the sludge of reality and using a black and white colour split effect (as below)?
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.
