I watched the video and I’d encourage anyone reading here to do so first before commenting. In fact, I’ve watched the relevant part of the video three times just to make sure I got a proper handle on what Tim Keller is saying.
The first thing I noticed was that it isn’t as confrontational as its title makes it out to be. In actual fact, he’s quite gracious about the matter. There are no snide remarks about “putting your trust in science” or “secular science” or “compromise” or any of the incendiary stuff of that ilk that you get from the likes of Answers in Genesis. He speaks of having been advised on the matter by scientists who are Christians, who have told him what the scientific consensus is, but he does not seem to be questioning the genuineness of their faith.
The second thing I noticed was that he’s completely up-front and honest about his position. He knows what the scientific consensus is but says that he believes he has to reject it in order to remain faithful to his understanding of the Bible. But he isn’t asking anyone to tell lies, or to misrepresent science, or to claim that they have scientific evidence when they don’t. For me, that’s the most important thing of the lot. If there’s one thing that needs to be a non-negotiable in discussions about creation, it’s honesty.
