Wow! Great article!
Each of the great Western monotheistic traditions sees God as truth, love, and knowledge. This should mean that each and every increase in our understanding of the natural world is a step toward God and not, as many people assume, a step away. If faith and reason are both gifts from God, then they should play complementary, not conflicting, roles in our struggle to understand the world around us. As a scientist and as a Christian, that is exactly what I believe. True knowledge comes only from a combination of faith and reason.
A nonbeliever, of course, puts his or her trust in science and finds no value in faith. And I certainly agree that science allows believer and nonbeliever alike to investigate the natural world through a common lens of observation, experiment, and theory. The ability of science to transcend cultural, political, and even religious differences is part of its genius, part of its value as a way of knowing. What science cannot do is assign either meaning or purpose to the world it explores. This leads some to conclude that the world as seen by science is devoid of meaning and absent of purpose. It is not. What it does mean, I would suggest, is that our human tendency to assign meaning and value must transcend science and, ultimately, must come from outside it. The science that results can thus be enriched and informed from its contact with the values and principles of faith. The God of Abraham does not tell us which proteins control the cell cycle. But he does give us a reason to care, a reason to cherish that understanding, and above all, a reason to prefer the light of knowledge to the darkness of ignorance.
As more than one scientist has said, the truly remarkable thing about the world is that it actually does make sense. The parts fit, the molecules interact, the darn thing works. To people of faith, what evolution says is that nature is complete. Their God fashioned a material world in which truly free and independent beings could evolve. He got it right the very first time.
To some, the murderous reality of human nature is proof that God is absent or dead. The same reasoning would find God missing from the unpredictable branchings of an evolutionary tree. But the truth is deeper. In each case, a deity determined to establish a world that was truly independent of his whims, a world in which intelligent creatures would face authentic choices between good and evil, would have to fashion a distinct, material reality and then let his creation run. Neither the self-sufficiency of nature nor the reality of evil in the world mean God is absent. To a religious person, both signify something quite different - the strength of God's love and the reality of our freedom as his creatures.
I must say that I DO believe in the supernatural reality of demons/angels only because I have experienced it. I would not rule out another plausible explanation of what I did experience, however.
