I bought this welcome biography last year when it came out but mislaid it and so have only just read it. I am eager to commend it to those who've not had a chance to read it, especially preachers. Macarthur is one of the major preachers of our day and apart from one or two aberrations stands where the best Reformed Baptists stand. The book's strength is that it is both informative and analytical. We get a full picture of the way the ministry has grown over the years and its present vastness. Murray clearly greatly respects his subject but is not afraid to criticise or disagree when he finds that necessary yet without getting in the way. He is also interested in the bigger question of what God is doing in all this. Our indebtedness to Iain Murray, which is already great, goes up anther notch, therefore.
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.
