It's a sermon about cities, and a sermon about seeds, but really it's a sermon about people's reactions to the Good News of Jesus Christ. It's also about trashing the neighbouring town of Barrhead. It's just a joke though, Barrhead. We love you, Barrhead, like Paul loves Thessalonica and Berea. We love you like Athens loves its idols and idle chatter. We love you like Angie loves giggling churchmice.
