If you believe you are guilty, it's because you believe you really did something which has caused a loss or damage to someone else. It means you believe you succeeded in attacking and taking something from them. The guilt tells you that because you did take something away from another (sinned), you owe them.
This means they are justified in doing something to you in return, in attempt to take back what you stole, and to retaliate against your crime. You now must fear revenge, and see it as an inevitable, constant threat. You believe in their likelihood of revenge because you believe in your success at sinning, hence your guilt.
So long as you believe that the person is suffering the consequences of your sin, which you want to believe because you want to have succeeded in separating, you will believe they are going to hunt you down and attack you. You believe they are completely justified in doing this and even agree with their motivations, even if it threatens you.
Therefore your guilt has automatically produced a state of fear, whereby simply because you are guilty, you yourself can see the sense in someone else wanting to attack you back. You believe in what you stole and see them as seeking revenge, to atone for the sin. Of this you must be afraid, and so guilt leads to automatic, mandatory fear of punishment.
The guilt will therefore automatically imply, project, and turn into fear. Now that you are in fear, you believe that you should be afraid, because you believe that punishment is going to come. And even though you yourself believe that you don't want the punishment to happen, you cannot help but be afraid it is going to happen because you already believe in the reason for it. It must happen, because you are guilty, and all your efforts will be to try to avoid and escape it, even though you believe it is inevitable. You attempt to escape BECAUSE you believe it is coming.
However, your own belief in your guilt will keep producing the fear, and the fear itself will keep visualizing the ways in which punishment is going to happen. At every turn it will haunt you and you will not feel safe, threatened by the revenge that you believe must be coming. In fact, so strong will be your belief that the punishment will come, that you will in fact begin to make it come. You will draw it to you, ask for it, and even take steps to make it happen. You will hate yourself for this but you yourself believe in the logical sense that you should be punished, and so you will agree to allow punishment to come to you, even if it makes you suffer.
Therefore because you have condemned yourself as sinful, it leads eventually to you implementing your own self punishment. Even if other people will not comply with your attempts to destroy yourself, you will do enough of a job on your own to ensure you receive what you believe you deserve. And so you will continue to prove your worthlessness by demonstrating that you deserve punishment, enacting it against yourself, and literally hurting your own self by your own hand.
And so fear inevitably leads to the enactment of punishment, because it strengthens the belief that you should be punished, and what you fear you attract. Fear pretends to not want what it focuses on, but it feeds tremendous energy into what it would avoid, through attempts at further separation, which only intensifies the sense of sin and guilt and produces more of the same. Eventually the shame and guilt produces so much fear of punishment that it starts to produce actual punishment. And so fear turns into punishment, sickness, and suffering, and perhaps even death.
Fear perpetuates and justifies a perception of yourself as being victimized, whereby whoever is to attack you is justified in doing so because of your sin. You owe them, and you know it. Therefore you dread the punishment that you yourself believe you should be receiving, and it's only a matter of time before it finds you. And if it is taking too long, one way or another you will cause it and welcome it, because you believe it is what should happen.
As punishment increases, so too is fear increasing, and gradually the atoning for sin nears completion. The more you are punished and suffering, the more you believe you are getting what you deserve, even if you exclaim that it is unfair and undeserved, and even if it is scaring you shitless. You yourself started this whole cycle through your own self condemnation, and your guilt and fear and punishment is just the fulfillment of your own belief in your worthiness of suffering. And so punishment comes and as it continues to ramp up in severity, so do you inflict upon yourself what you think you are worth.
The final blow of punishment is of course death, the idea that your sin is so great and so irreversible that you might as well give up on life completely and just let yourself be caught by those who you believe would bring the punishment to you. You surrender to death and lay down your life as though it is simply inevitable, because there is absolutely no way out of the logical sequence of conclusions you come to as soon as you start down the slippery slope of sin. Here you have followed sin to its logical conclusion, the call for atonement in death. The sinful must die, and the inescapable progression of logic from sin to death gives no way out, regardless of your protests.
This need not be.
The Son of God is not sinful. You are not guilty. And you have no reason to be afraid. Sin is not real, and no matter what you did, it is forgiven already by God. It wasn't reality and it didn't happen in reality. Only in a dream. Wake up to the happy news that all is forgiven and you are welcome home.
The progression of unfolding from sin through guilt fear punishment and death, need not occur, if the root foundation of that entire thought system is dug out. You must be willing to question whether the sin was real, whether you really did separate from God, or whether nothing has happened. This is the undoing of the dream of death, and is what the atonement represents. The idea of truth, that you cannot possibly separate from God, your attacks cannot have any effects, you cannot really sin, and no real consequences have come from trying.
You still remain as innocent as God created you to be. All the rest is just delusional nonsense and dreaming. You don't deserve to die. You deserve to live forever.
