Believing you are guilty for that sin is an attack on YOU, not a guilt imposed by whoever you thought you sinned against or how they would judge you, but by your own self against yourself. God does not find you guilty.
Believing in fear because of your guilt is also an attack on YOU, by yourself, not a fear induced by who you sinned against, or because they will retaliate, but a fear that you will deserve your own punishment because of the guilt that you believe you deserve. God is not making you afraid.
Believing in punishment because of your fear is once again an attack on YOU, by yourself, and not an attack coming at you from anyone else for any reason. It is your way to pretend to use others as ways to punish yourself, all the while pretending that you are not the one doing any of it. You are afraid of YOU and your self punishment. God has no desire to punish you and you're doing such a good job of doing it to yourself that He doesn't need to.
You sin against you. You make yourself guilty. You are afraid of yourself. You punish yourself. That's how it goes.
Nowhere in this equation is anyone else involved in any direct causal way without your consent whatsoever. Nobody. Because there is only you, doing this to yourself.
Why are you doing this to yourself?
Are you done with self attack yet, or the fake story that it's everyone else who is against you? The only one against you is you, as your own enemy.
What if you were to stop attacking yourself? What if you decided you are forgiven? What if you realized and recognized that you DID NOT SIN? That your sin did nothing to anyone but yourself? That nobody else separate from you was sinned against, caused guilt, induced fear, or dealt out punishment. What if there is only you and your war with yourself?
The war with yourself cannot be 'won', because then you lose.
Is it time for peace?
The secret to salvation is this... that you are but doing this to yourself!
