We finally got to the end of 2 Timothy 2 last night, looking at verses 23-28. These verses are ostensibly about dealing with opposition but more broadly they reveal the character of the minister and the ministry and what aim is. This applies not only to dealing with opposition but more generally to all efforts to reach out. We are seeking to see in opposers and unbelievers repentance, coming to their senses, knowing the truth and escaping from the devil's trap. We had a good prayer session too.
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.
