Some time ago there was a popular bumper sticker going around. It read, "God said it, I believe it, that settles it." Good, solid, Bible-believing bumper sticker. All well and good. Unless, of course, you think it through. This sticker begs the question.
Take a look at it for a moment. The conclusion is that something is settled. The question is what settles it? The statement suggests two things are required to settle it -- God said it and I believe it. Do you see the problem? This has placed "I believe it" on equal footing with "God said it." It is possible that "God said it" and "I don't believe it" and it would not then be settled.
Now, of course, it's just a bumper sticker. Not really a doctrinal statement. We can let it go. But we must not let go of the base issue. Is "God said it" sufficient to settle it? Which comes first, "God said it" or "I believe it"? Is my belief required for something to be settled? Sure, it may require my belief for it to be settled for me, but we need to acknowledge that "I believe it" is not required for "it" to be settled. That is, it is settled and what is necessary now is for me to believe it.
It's only an illustration of the basic problem today. We hold God's Word up for examination. "You know," our world tells us, "those Christians who believe that it's a sin to have sex outside of marriage are out of step and wrong." "But," a Christian might answer, "if I am to follow Christ, I have to follow His Word, so I have to go along with that." "No, no," they assure us. "Clearly that part is wrong and needs to be discarded/amended." And we do. To our own peril. Because if God said it, it is settled. And yet there are too many -- including self-professed Christians -- who determine what is or isn't true by "what I believe" rather than by "what God said."
Yes, it's only a sticker. And, in fact, I don't see it much anymore. So the sticker problem is nearly gone. The idea remains. If we were to be rational Christians convinced that God is true though every man a liar, then we would need to hold a different position: "God said it, that settles it, I believe it." For the rest of the world, whether they are unbelievers or self-styled believers, snatching up the right to evaluate God's truth and determine where the Word is wrong based on their own personal preferences is an arrogance we should all be wary of.
