I think we live in a world of true becoming, and I think that God relates to time - the God of the Bible is terribly immersed in time - and that God knows that if the world is truly a world of becomingness, then God knows it is, in its becoming.
What a monumental pile of gibberish. Polkinghorn must wake up every now and then and realise that he is a fraud, that his entire intellectual life is founded on childish myths. But rather than face up to this emptiness, he spouts gibberish like this in the hope that ordinary people will find his philosophical mumbo-jumbo impressive and say that if a (former) Cambridge professor of physics thinks this, then it must be right.
Well, prof, you’ve been rumbled. Cut the pompous intellectual facade and admit that you’re a meaningless member of a meaningless species on a small planet on the outer reaches of a universe with at least 10^24 similar planets. We don’t know how this came to be and we never will, but the ‘God (who) knows that the world is truly a world of becomingness’ certainly didn’t create it because he only exists in your delusions.
