I will sprinkle clean water upon you, and you shall be clean from all your uncleannesses, and from all your idols I will cleanse you.
A new heart I will give you, and a new spirit I will put within you; and I will take out of your flesh the heart of stone and give you a heart of flesh.
And I will put my Spirit within you, and cause you to walk in my statutes and be careful to observe my ordinances.
Ezekiel 36. 25-27
Makes me wonder what all the fuss about free will is about. ‘I will put my Spirit within you,’ says the Lord, ‘and cause you to walk in my statutes and be careful to observe my ordinances.’ I will cause you to follow the law: this is how God consoles a wayward, hard-hearted people–not by relaxing the law or even by forgiving and forgetting. The Lord forgives, but does not forget: he remembers that we are but dust. He washes our sins away but remembers our fallen condition and provides for us accordingly. As St Paul observed, at the right time, while we were still sinners, Christ died for us.
In Christ we have more even than what Ezekiel promises: a paradigm. Christ is the one with the heart of flesh; he is the one in whom the Spirit dwells fully; he is the one who keeps God’s law perfectly; and he does this all freely. That is the work of the Spirit, to restore our freedom. God does not cause us to follow the law by thwarting our will and desires, but by healing them, transforming them. Under the Spirit’s guidance, we do not act as puppets. We act as we were created to act. We live according to our creation in the image of God. The Spirit does not cause us to follow an alien law, but the law that has been written on our hearts.
I suppose this is the natural law, in the view of philosophers who study such things. It is the law, that is, of our nature. In our fallen state, however, being true to our nature as creatures of the living God requires grace. Fortunately, it seems pretty clear, from Genesis all the way through, that grace is exactly what God wants to give us.
