Ron Hughes: David, I hear people decry the narcissism of our age and the fact that people are so concerned with themselves. And yet I can't help but be aware of the fact that one of the things that draws my attention to God is, me. The fact of my existence. The fact that I exist means to me that there's somebody else.

Dr. Humphreys: That's basically the one unsolved puzzle of science. I mean, we're here and we have to explain that. And we all do that, we look at ourselves and our existence and we say, "Why am I here?" We feel that big hole where God should be. I mean, without God, without that creator, it is like this jigsaw with a piece missing.

But you know, I just find, not only just thinking about myself and my family and life in general, Ron, that I'm so grateful to have a relationship with God. I mean, it's not just selfishness. When you as a person are feeling the joy of life and the beauty of life and you're enjoying your relationships in your family and so forth and you're feeling grateful, who do you thank?

I mean, I often look at my non-believing colleagues and say, ‘you know, it's tough when you're feeling joyful and grateful that you've no one to thank.' You see, and part of my life is motivated by the fact that I have someone to thank. You see, because I can't just be an armchair scientist gazing at the cosmos and saying ‘aren't the stars wonderful.' I mean, it's like the cosmos winks back at me and I say, there's a relationship there. There's someone there. And it's good to find Him. I mean, just like it's nice to know eachother, it's nice to know the Creator. So there's a personal dimension to all this.

You know , Ron, I'm a scientist and I believe in experiments and checking things out. And I just hope that the people listening to this broadcast would try the experiment that I tried when I found the Lord; when I was able to thank the Lord for what He's done for me. Because the Bible always says, ‘taste and see that the Lord is good.' (Psalm 34) And that's the invitation to try it out. Because for me it's just a source of joy, it's just a source of thankfulness to have that relationship. So it's really not that selfish. It's actually the giving of yourself to a new relationship when you find the Lord.

Ron Hughes: David, you've shared a lot of things about science that are special to you. Could you share something from the Bible that is special to you?

Dr. Humphreys: Well, in terms of what we've been talking about, Ron, you know, the bottom line for me is the great verse in Revelation 4:11 - the ultimate, grand unifying theory if you like - the bottom line explanation and the motivation for me as a Christian is this verse that says:

"Worthy are you O Lord, to receive glory and honour," and it says, "For you did create all things. For your pleasure they are and were created."

That's a statement of fact - He created all things. There's a reason - for His pleasure. And it's just been a privilege for me to recognize the real reason: the worthiness of the Lord. And that's just a great verse, because it brings together, not only the statement of fact - that He's the Creator, and the reason - for His pleasure, but it calls us to respond in worship. Because science is objective and we tend to do it without thinking of the emotions, but the Lord calls us to a response; to worship Him. So I just share that verse, "Worthy are you O Lord, to receive glory and honour."
