One must dig deeply into opposing points of view in order to know whether your own position remains defensible. Iron sharpens iron.

It's interesting when you read the life of Christ how much of his time he spent healing the sick. There must have been a reason for that - he was modelling for us what it is we are intended to do by following his path.

The problem [with genetic research] is, we're just starting down this path, feeling our way in the dark. We have a small lantern in the form of a gene, but the lantern doesn't penetrate more than a couple of hundred feet. We don't know whether we're going to encounter chasms, rock walls or mountain ranges along the way. We don't even know how long the path is.

I had the analysis of a million or so SNPs [single nucleotide polymorphisms] just to see what was there. That's partly because I was writing a book about DNA and personalized medicine and I thought it would be a little bit disingenuous to talk about what could be done without actually having the experiment done on yourself.

I believe God did intend, in giving us intelligence, to give us the opportunity to investigate and appreciate the wonders of His creation. He is not threatened by our scientific adventures.

What more powerful form of study of mankind could there be than to read our own instruction book?

What wakes me up at night is this next generation and what's happening to them. And they're invariably excited about the science that they're doing, but invariably anxious about where there's a future.
