RJS, a scientist and a Christian, has had a very good series on faith and reason at Jesus Creed. It is following Tim Keller's new book, The Reason for God. I thought that the latest essay was worth noting:
We are wrong to believe that we will ever construct an irrefutable argument or proof for the existence of or the nature of God. This is an impossible task. Rather we will look at preponderance of evidence and the viability of a Christian world view, taking into account all of the evidence we have available. Even in science we have no absolute proof – only empirically based theories that organize and explain the evidence better than anything else available. A theory is accepted if it explains and predicts — a theory is refined and improved, sometimes substantially, sometimes incrementally, in the light of new evidence, observation, and information. Keller says:If the God of the Bible exists, he is not a man in the attic, but the Playwright. That means we won’t be able to find him like we find a passive object with the powers of empirical investigation. Rather, we must find the clues to his reality that he has written into the universe, including us. That is why, if God exists, we would expect to find that he appeals to our rational faculties. … It also means that reason alone won’t be enough. The Playwright can only be known through personal revelation. (p.123)
