There is in human beings a charming and naive desire to create new things ex nihilo, to go back to the garden as it were, to start again as though we have not already done anything good or bad.
In part, this drive arises from the presence of the image of God in us. He creates ex nihilo. We are His image. So we want to be able to create ex nihilo. And who knows, maybe there will come a time when we can. Maybe there is even some relative sense in which we can now.
