From John (St. Andrew’s Expositional Commentary) by R.C. Sproul:
I’m sure you’ve seen the popular bumper sticker that says, “God said it; I believe it; that settles it.” How arrogant is that? We need a new bumper sticker, one that says: “God says it; that settles it.” It doesn’t matter whether I believe it. It’s settled long before my assent. If God Almighty opens His holy mouth and declares something, we don’t need another witness. It’s over.
