If sin is a lowering of consciousness from divine, to human, to demonic, then God, in creating this universe, committed the first sin. God is the First and Last of sinners.
Perhaps this is why he is so obsessed with redemption. He needs to redeem himself through the passage of human history, where God finally gets to remember himself as God, as time, as Being-in-itself.
Maybe when we can finally forgive God for his fall, and compassionately tell him with hearts full of love, “It’s okay, God. I understand. I love you as you are,” then perhaps he will be able to forgive himself for his big fall and learn to enjoy his creation a little more, trusting his children a little, and allow us the space to become, as he becomes.
