I thought our numbers may be down a bit yesterday with people off to college but it wasn't bad morning or evening with a few visitors as well as regulars. One new thing yesterday was that we church officers and families made a fresh effort to be there early and that made a difference. I completed 1 Corinthians 9 in the morning - the famous by all means to save some section. In the evening I was comparing Jonah overboard with the death of Christ. I now have an assistant (Andrew Lolley) and I had him read from Scripture I the morning and lead in prayer in the evening.
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.
