I’m not an expert in this question. There may be better thought out answers out there. But here goes my own musings.
I think there must necessarily be an irreversible consequence to every true act of freedom, for that act to be considered an act of freedom. Let me explain.
If every time a little boy broke something, his parents would punish him for a time, but whatever he broke would always be magically restored, then there was really no true loss as a result to his irresponsible action. Yes, he would learn that certain actions are wrong because they are not pleasing to his parents, but not because they have real power to beautify or to destroy. In fact, that everything he destroyed could always be fully restored affirmed to him that as long as he came back to his parents, it really did not matter what he did. In the end, he might not learn anything regarding exercising his freedom, because his acts would not be completely free anyway, since everything would be restored the moment he repented.
Similarly with God, if God simply snaps His fingers and resets everything back to the original state every time we repent, I wonder if we would learn anything permanent. For one thing, it would not matter much what I destroy, including human life and personal honour and dignity. And can we still call ourselves free if there is no loss for bad action, since that would also imply there is no real fruit with good action?
God made us in His own image. God’s image is: His word and His action are one and the same thing, what He says, is. He gave us the same freedom, to participate in that same power: what we choose must have some permanent consequences, for us to be truly free, to be truly human. He gave us that awesome power, because without true freedom, there is no possibility of true love and true sacrifice.
Salvation and redemption, therefore, is not resetting everything to the original state. It is not possible without also taking away our humanity, and reducing us to mere animals. What God has instead is something better in spite of us destroying that original plan. God came among us, Emmanuel, Jesus. He is fully man and fully God. He embodies how it is possible to be fully man, to be able to fully overcome human weaknesses by completely surrendering Himself to the Father. He demonstrates daily to us that we too can do the same, so long as we daily surrender ourselves to Jesus. Salvation will not come to us as automatic integrity and prevention as original justice, that possibility was destroyed by us. Salvation will now only come to us through us longing and struggling and fighting to cooperate with Christ daily. The bonus is: before it was a given that we did not merit, now it is a gift that we also merit and so co-own with God.
