A first piece on the God and Physics, John Polkinghorne conference is up at the Guardian's Cif belief. A taster:

It's with that recognition that there is a possibility of giving an account of divine action within nature, which is compatible with science. It relies neither upon a God who intervenes outside the usual play of nature, nor seeks low-level causal gaps. Rather, God's action could be viewed as analogous to top-down, emergent causation – particularly when it implies signs of purpose or intentionality.

An obvious – though obviously contentious example – could be the relationship between mind and the neural components of the brain. To put it simply, if neurons affect our consciousness from the bottom-up, mind might be said to do so from the top-down. That'd be one way of understanding human agency. Divine agency could be described by analogical extension.
