"I must have decided wrongly because I am NOT at peace."
This means that if in ANY WAY I am not at peace, am sick, upset, unhappy, afraid, in pain, suffering or dying, it has come about ONLY because *I* made a wrong decision. This "consequence" is showing up ONLY because of the power of my own decision. I put it there. I made it happen to myself. There are no other causes. I am responsible for having attacked myself. I decided wrongly and it produced these effects. I must claim responsibility and ownership of this power to choose what I experience and stop blaming others.
"I made the decision myself, but I can also decide otherwise."
This is further compounded in this second line - that *I* made the decision myself. Which means, the secret to salvation, I did this to myself. I am not unhappy because of something someone else did or something that happened to me against my will. I made a DECISION, on my own, which was a poor decision, which was a DELIBERATE decision, to choose ego and suffering, on purpose. I have to own that. I made myself suffer and unhappy. I chose it.
Then once I can see that I own that fully, I can now realize that, in spite of this, I can change my mind and "choose again". Acknowledging that I chose this in the first place puts me in touch with the power to choose. Owning the choice I MADE allows me to own my power of CHOOSING and therefore puts me back in touch with my power to choose a different experience. And whatever I choose, I will receive.
"I WILL to decide otherwise, because I WANT to be at peace."
Notice in the early version it says I *WILL* to decide otherwise meaning I actually DO IT, whereas in the FIP version they changed it to "I want" which is somewhat removed from actively DOING it. And so now you are realizing, that you no longer want what YOU CHOSE, you no longer want the suffering YOU MADE HAPPEN, and so now you WILL - choose - actively -towards a more sane decision which will results in consequences of peace instead of conflict.
"I do NOT feel guilty, because the Holy Spirit will undo ALL the consequences of my wrong decision IF I WILL LET HIM."
You now recognize clearly that you have not sinned, and merely have been mistaken. Mistakes can be corrected and they call for forgiveness, not punishment. Therefore you do not need to be guilty, which isn't helping anyone. Guilt is not love or a change of mind. I also don't have to worry about all the giant fuck of a mess that I made, myself, that I did to myself, even if that means having attacked myself and made myself sick or suffering or in pain or half dead.
Whatever the consequences of my wrong decision were, whatever the MANIFEST EFFECTS were, THEY can be undone. AND they can be undone BY the Holy Spirit through supernatural healing means. And the only thing remaining to ALLOW this to occur is my own willingness to LET HIM HELP ME. There is no consequence He cannot undo, including incurable diseases, and including death.
"I WILL to let Him by allowing Him to decide for God for me."
Again this says that I WILL, whereas I think in a later version it was changed to "I choose". We need to realize that WILLINGNESS is very important because it indicates full commitment and POWER. Your choice and your will are very powerful and your mind is powerful. This isn't merely an inert, neutral, powerless small decision. It is a choice to OPT for and CLAIM a different experience. If you change your mind, the whole world must change. You are ruler of the universe! Nothing happens that you do not choose and whatever you choose MUST HAPPEN.
Additionally, when you ALLOW Holy Spirit, you invite him into you, you let him help you, you ask for His healing and you RECEIVE the truth (atonement), He can AND WILL AND DOES come into you and can heal ALL OF THE CONSEQUENCES that you produced in your wrong decision. He can heal all pain and sickness and suffering. And you must be WILLING to let him, to trust him, to allow him, to give him permission, in order to have him take your INVITATION and come in to heal you and clean up the mess.
He is here to HELP YOU and you do not have to tolerate suffering of ANY kind, and you do not have to put up with consequences you caused, and you do not have to stay sick, and you do not have to do this all on your own. Allow yourself to RECEIVE THE LOVE that you now choose and WILL and accept as a sane decision. Love will heal you AND your body.
