I think there are a lot of pop songs where you could just throw in an occasional “Jesus”, and most people would never notice that they aren’t actually about anything remotely Christian. Try it sometime. For instance:
I’m reading a book right now called “Why Johnny Can’t Sing Hymns: How Pop Culture Rewrote the Hymnal”. So far it’s great. It’s gotten me thinking, though… we really do listen/sing very uncritically, don’t we?
