I was at the annual meeting of the American Scientific Affiliation (the fellowship of Christians in Science in the USA) a couple of weeks ago. One of the talks that I heard was by Gregory Bennett, a geologist – and I’d be interested to hear what the theologians and philosophers think of it.
God’s providence – the way in which he acts in the universe – provides a basis for science and technology. The fact that an experiment gives the same result today and tomorrow has to be taken for granted or you couldn’t do science – it just happens, and that’s why we have ‘laws of nature’. But within a Christian worldview that makes perfect sense.
Gregory Bennett put forward a detailed analysis of providence:
- God constantly sustains the world so that the properties of things are preserved.
- God cooperates with created things, directing their distinctive properties to cause then to act as they do.
- God directs all things to accomplish his purposes.
So God is very hands on and ‘does’ everything – even making my pen fall to the ground when I drop it. This is a very active kind of sustaining, and is consistent with the language of God sustaining and providing rain, food and so on that occurs throughout the Bible.
I have sustained him with grain and new wine (Genesis 27:37)
He covers the sky with clouds; he supplies the earth with rain and makes grass grow on the hills. (Psalm 147:8)
He provides food for the cattle and for the young ravens when they call. (Psalm 147:9)
Bennett described ordinary providence – working through ‘secondary causes’ that we can understand scientifically in terms of the regular operation of things in the world, and extraordinary providence – where no secondary cause can be seen. Extraordinary providence would be a miracle (in my opinion not the only kind of miracle – I think miracles of timing also happen) – something that draws attention to God and his interaction with us.
