Wednesday I spent 6 hours on the road, a little short on sleep. I had some young companions and the drive was broken by the usual bathroom breaks, nursing breaks, and a stop for gas/food – not to mention the normal chit-chat, so I didn’t have to fight drowsiness.
Today I was behind the wheel again, this time with much less sleep. Fortunately I had Greg Bahnsen to keep me company. We love Greg Bahnsen’s lectures about philososphy and how to defend the Christian worldview against those who hold to atheism, evolution, and other fairy tales.
We love it so much that when I started playing it, there were calls from the back of the van to turn up the volume. Dr. Bahnsen is brilliant, but he is also entertaining and easy to understand. He makes you feel smart. You can do this.
His primary approach in debating worldviews is to direct the discussion back to its foundation – to force his opponent to acknowledge the presuppositions upon which all of his arguments rest. There is no neutrality, and atheists are no less creatures of faith than Christians. All of their beliefs, like ours, are ultimately based upon one underlying foundation. The question is, “What is your ultimate authority?”
I wanted to take notes as he spoke, but I know better. Typing/texting while driving = Colossally Bad Idea. No lecture necessary on that point.
There was something he said and repeated for emphasis, and I really wanted to remember it but I forgot. I’ll have to listen to that message again. I was more careful with the next statement that caught my attention, and repeated it to myself several times as he elaborated and expounded: All ultimate authorities must be self-authenticating.
Did you catch that?
When unbelievers ask us how we know the Bible is the true, infallible Word of the One True God, we can answer that we know because the Bible tells us. When you’re talking about an ultimate authority, you’re at the top of the food chain. If you can go any higher, then you’re not at the top yet.
This applies to unbelievers as well. Ask how they know what they know. Keep asking, “But how do you know?” until they reach the top.
Is it science? But how do they know the current research and theories are correct?
Is it their own eyes? Don’t they believe in many things they’ve never personally witnessed, like the existence of cells, atoms, or 3 toed sloths in the wild?
Is it their own opinion, or the majority opinion? Opinions change.
For most unbelievers, it comes down to logic in the end. And how do they defend the assertation that logic is the true, final answer? By use of logic, of course. How else? Their ultimate authority, like ours, is self-authenticating.
The difference is that they have faith in the authority they choose, while objecting to ours. This is not logical; it’s arbitrary, a foundational flaw in their reasoning. This is a failure to apply sound logic, their self-proclaimed god. You’ve got ‘em now.
Intrigued? You should be. He also clearly explains why Christians can appeal to logic but unbelievers can’t, and countless other such traps that your hapless victims will set for you and walk right into. OK, maybe I’m being a little flippant, but I’m not exaggerating. Now you have a taste of why we love these lectures.
