When humans sin, they hand to nondivine forces a power and authority that those forces were never supposed to have. And that is why, if God’s plan is to rescue and restore his whole creation, with humans as the active agents in the middle of it, “sins” have to be dealt with. That is the only way by which the nondivine forces that usurp the human role in the world will lose their power. They will be starved of the oxygen that keeps them alive, that turns them from ordinary parts of God’s creation into distorted and dangerous monsters.
