The point in Christianity which gives us the greatest shock is the statement that by attaching ourselves to Christ, we can ‘become Sons of God’. One asks ‘Aren’t we Sons of God already? Surely the Fatherhood of God is one of the main Christian ideas?’ Well, in a certain sense, no doubt we are sons of God already. I mean, God has brought us into existence and loves us and looks after us, and in that way is like a father. But when the Bible talks of our ‘becoming’ Sons of God, obviously it must mean something different. And that brings us up against the very centre of theology.
One of the creeds says that Christ is the Son of God ‘begotten, not created’; and it adds ‘begotten by his Father before all worlds’. Will you please get it quite clear that this has nothing to do with the fact that when Christ was born on earth as a man, that man was the son of a virgin? We are not now thinking about the Virgin Birth. We are thinking about something that happened before Nature was created at all, before time began. ‘Before all worlds’ Christ is begotten, not created. What does it mean?...
To beget is to become the father of: to create is to make. And the difference is this. When you beget, you beget something of the same kind as yourself. A man begets human babies, a beaver begets little beavers and a bird begets eggs which turn into little birds. But when you make, you make something of a different kind from yourself. A bird makes a nest, a beaver builds a dam, a man makes a wireless set - or he may make something more like himself than a wireless set: say, a statue. If he is a clever enough carver he may make a statue which is very like a man indeed. But, of course, it is not a real man; it only looks like one. It cannot breathe or think. It is not alive.
