Good congregations once again morning and evening, helped by visitors. (The presence of just two families in the evening meant an extra 12 people, more or less doubling the congregation). I preached from the last chapter of Acts in the morning and the end of Matthew 27 in the evening. The subjects of common grace and the burial of Christ are unusual subjects but worthy of being dealt with on the Lord's Day. E had communion in the evening and that went off quite well, although I could have made a better hymn choice. I felt particularly full of the Spirit in the morning but less so in the evening.
The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. 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.
