It was the first Sunday of the month so we started with communion as we usually do. We always sing unaccompanied. I love that, especially when I manage to pitch them right. I then preached on Psalm 139 to quite a large congregation including a nice little group of five kids who I talked to beforehand on the first commandment. There were several visitors including one or two new ones. We were a much smaller group in the evening and it was tempting to get discouraged but I sought not to and afterwards one or two had things to say following on from the sermon (on Matthew 7:1-6) and that always helps.
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.
