I couldn’t choose, so here are several gems to choose from:
“Biblical inerrancy can’t hold off demographic realities forever” (Bill Leonard)
“I’ve said it before: the surprising thing isn’t that creationists are dishonest; it’s that, with all the practice they’ve had, they aren’t any better at it” (John Pieret).
“If you don’t like change, you’re going to like irrelevance even less” (General Eric Shinseki).
