His article in the Daily Mail several weeks back is itself excellent:
But, as both a scientist and a Christian, I would say that Hawking's claim is misguided. He asks us to choose between God and the laws of physics, as if they were necessarily in mutual conflict.
But contrary to what Hawking claims, physical laws can never provide a complete explanation of the universe. Laws themselves do not create anything, they are merely a description of what happens under certain conditions.
What Hawking appears to have done is to confuse law with agency. His call on us to choose between God and physics is a bit like someone demanding that we choose between aeronautical engineer Sir Frank Whittle and the laws of physics to explain the jet engine.
