Conrad finished off on the second two mornings by looking at the final phrases in 1 Timothy 3:16 (was seen by angels, was preached among the nations, was believed on in the world, was taken up in glory). Once again using a God exalting style illustrating chiefly from Scripture itself, it was fine preaching of the Word. He took the seeing by angels as taking place in heaven after the ascension and the taking up in glory as referring to the final consummation and so we ended on a very high note in what I thought was the best of the four mornings.
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.
