It was a privilege to be preaching God's Word again yesterday. I had expected numbers to be down as I knew a lot had left for holidays and camps and beach missions but with visitors we had decent (for us) congregations morning and evening. In the morning we went back to John 3. I think John 3 is one of those chapters we ought to keep coming back to. In fact, after I'd made fresh preparations I noticed that in Autumn 2012 and I had done a nine sermon series on the verses as far as 21. By taking a larger chunk I was able to speak about regeneration and justification not just one or the other. In the evening we were in Matthew 7:21-23 (almost at the end then) and the matter of Christians false and true. We ended up with quite searching sermons then. We need more of that I guess.
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.
