We looked at just one verse again last night - Philippians 4:9, Whatever you have learned or received or heard from me, or seen in me--put it into practice. And the God of peace will be with you. In a quite wide ranging presentation I urged us all to take greater advantage of the ministry we receive. We were able to spend a good time in prayer.
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.
