Satan hath three titles given in the Scripture, setting forth his malignity against the church of God; a dragon, to note his malice; a serpent, to note his subtlety; and a lion, to note his strength. But none of all these can stand before prayer. The greatest malice of Haman sinks under the prayer of Esther; the deepest policy, the counsel of Ahithophel, withers before the prayer of David; the largest army, a host of a thousand Ethiopians, runs away like cowards before the prayer of Asa.
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.
