The idea of death was made as the opposite of the idea of God. The separation from God was total opposition to God's nature. It's an assertion that God does not exist, blotted out and dead.
Whatever attributes God has, death is the idea of the total absence of all of those attributes. A total lack of life, of love, of happiness, of peace, of sharing. Anything that God is, death opposes.
"The thought of death is ... the opposite to thoughts of life." UrW167L8
God is creation, and so death is destruction. God is permanent, and so death is change. God is love, and so death is murder. God is reality, and so death is an illusion.
In order to oppose God, the truth must also be opposed. That which is false is asserted as true. True and false become swapped. The truth of God becomes a lie, and the lie of death becomes a reality.
As a result, all of the attributes of God are assigned to death, while all the attributes of nothingness are assigned to God.
Death is now seen as inevitable, real, permanent, eternal, irreversible, powerful, known, true, dependable, trustworthy, welcoming, wanted, attractive, loved, salvation, peace and happiness. God is now seen as uncertain, changing, vulnerable, hateful, vengeful, nothing, meaningless, lifeless, mindless, unloving, destructive, dark, murderous, unwanted, rejecting, an enemy, selfish, unsharing and unreal.
The result is that we have a belief in death, which takes on every possible form. It takes on physical form, as well as in the form of changes of mind, states of feeling, types of thoughts and senses of identity. Every illusion, all of space and time, every perception arises in the idea of God's opposite.
"Embodiment of fear, the host of sin, god of the guilty and the lord of all illusions and deceptions, does the thought of death seem mighty. For it seems to hold all living things within its withered hand; all hopes and wishes in its blighting grasp; all goals perceived but in its sightless eyes. The frail, the helpless and the sick bow down before its image, thinking it alone is real, inevitable, worthy of their trust. For it alone will surely come." UrW163L2
"Death is the central dream from which all illusions stem. Is it not madness to think of life as being born, aging, losing vitality, and dying in the end?" UrM28A1
Anything less than the true nature of God is a form of death. This includes any sense of unhappiness, any notion of attack, any kind of sickness, any temptation, any desire for bodies, any false perceptions, any fear or guilt, any idol worship and any way that you see yourself and others as less than having eternal life.
There can't even be atoms and molecules and bodies and planets without the idea of death. Death is change and change is time and time is death. To be separated from life, from God, is to enter into an illusion of dying. Spacetime is the idea of the death of God, in which God appears to not exist.
"The world was made as an attack on God. It symbolizes fear. And what is fear except love's absence? Thus the world was meant to be a place where God could enter not, and where His Son could be apart from Him." UrW230W32
"And the last to be overcome will be death." Of course! Without the idea of death there is no world. All dreams will end with this one. This is salvation's final goal; the end of all illusions. And in death are all illusions born." UrM28A6
Every aspect of ego, every form of separation, every unloving relationship, every body worship is all a form of death. If you believe in anything but God's reality you believe in death and are trying to die. We came into this world precisely because we wanted to play with death and to pretend that we can die. We are immortal beings, making a world that is always dying in which we can pretend to die.
"You who perceive yourself as weak and frail, with futile hopes and devastated dreams, born but to die, to weep and suffer pain, hear this: All power is given you in earth and Heaven. There is nothing that you cannot do. You play the game of death, of being helpless, pitifully tied to dissolution in a world which shows no mercy to you. Yet when you accord it mercy, will its mercy shine on you." UrW191L9
Undoing death is resurrection. To resurrect is to side with eternal life and reject every form of death. Sickness, which is "a little death", must be forgiven and reversed. Death of a body must be reversible. And an entire world rooted in death must be undone. Without the idea of death, spacetime cannot exist. And without death, there is no world and no separation from God.
"This aching world has not the power to touch the living world at all. You could not give it that, and so, although you turn in sadness from it, you cannot find in it the road that leads AWAY from it into another world." UrT12G3
"Death is the symbol of the fear of God. His Love is blotted out in the idea, which holds It from awareness like a shield held to obscure the sun. The grimness of the symbol is enough to show it cannot co-exist with God. It holds an image of the Son of God in which he is "laid to rest" in devastation's arms, where worms await to greet him and to last a little while by his destruction. Yet the worms as well are doomed to be destroyed as certainly. And so do all things live because of death. Devouring is nature's "law of life." God is insane, and fear alone is real." UrM28A3
"The idea of the death of God is so preposterous that even the insane have difficulty in believing it." UrW163L7
"There is no death. The Son of God is free." UrW163
"There is no death, and we renounce it now in every form, for their salvation and our own as well. God made not death. Whatever form it takes must therefore be illusion. This the stand we take today. And it is given us to look past death and see the life beyond." UrW163L8
"There is no death, for death is not Your Will. And we abide where You have placed us, in the Life we share with You and with all living things, to be like You and part of You forever." UrW163L9
In the separation, you confused the true and the false. You assigned God's properties to the false world, BUT YOU ALSO assigned false properties to God. This turned God into an evil enemy to you in your perception of him. This was necessary in order to believe that the world you made was something you would want instead.
This means you actually framed God as opposite to his nature. As if God is evil, destructive, attacking, sinful, deadly, sick, suffering, weak, powerless, unreal, illusory, vengeful and special. While many people focus on how they are going to forgive the false world, which entails lifting truth from it, you ALSO have to forgive God and lift the FALSE from him.
You may not realize that you have assigned false properties to God. But you have in fact framed God as a special false God. You have tried to make out that God is evil and an enemy. The ego believes this. It wants nothing to do with God because IT believes and perceives God as "everything evil", while seeing itself as holy.
"No-one who hates but is afraid of love, and therefore MUST he be afraid of God."
"You are more afraid of God than of the ego, and love cannot enter where it is not welcome."
"And being deceived in yourself you ARE deceived in your Father, in Whom no deceit is possible."
This means you do in fact have within you various reasons to avoid God, to fear God, to not want God, and to hate God. Part of you wants God to be dead. You have to therefore actually forgive God of the projections and misperceptions that you have laid upon him, and recognize that he is not those things.
It is your attempt to AVOID looking at your "attack on God" blasphemy that compels you to focus on forgiving the WORLD instead. You do not want to look at this because you actually believe that your attack on God has made you GUILTY. And you do not want to revisit the idea of approaching God because you believe it means admitting to having sinned against him, and you think he's going to kill you for it.
"You do NOT see that EVERY sin and EVERY condemnation which you perceive and justify IS an attack upon your Father."
"Your brothers and your Father have become VERY fearful to you, and you would bargain with them for a few special relationships, in which you think you see some scraps of safety."
"For through guilt, you EXCLUDE your Father and your brothers FROM yourself."
"It is your Father Whom you would defend against."
If you think that God is evil you will not want to go home. If you think the world is NOT evil you will not want to go home. You've turned God into an enemy and do not trust him. That's why there is a whole process of "the development of trust". You have misplaced your trust in the ego world. You have to learn to trust God again.
"You CHOSE to forget your Father, but you did NOT will to do so."
To trust God you have to be willing to accept the possibility that God is not the scary monster that you think he is. That he is not going to hurt or attack or reject you. That he still loves you because he is still love. You have to take away from God the false accusations you've made that he is evil and vicious and not to be trusted. You have hurled abuse at God and have accused him of sin. This has to be undone.
You will only approach God, tentatively, if you can have a little willingness to be mistaken about him. And this requires that you trust and have faith that he isn't out to destroy you. You have to be wrong about God, because you have become mistaken about him and his nature. You cannot conceive of him without a body, or think of him as anything but selfish like your ego. This has to be reversed.
"And either the ego, which you made, IS your father, or its whole thought system will not stand."
"Your gods are nothing, because your Father did not create them." "You who have been unmerciful unto yourselves, do not remember your Father's love."
This aspect of forgiveness doesn't seem to be talked about very much in ACIM circles. A lot of time is spent talking about forgiving the world and its contents and the people that piss you off, but very little about looking at the fact that you rejected God, hate God, do not want God, and are trying to destroy him and his son. This picturing of God as an enemy has to be undone in order for you to feel safe to be intimate with God again.
You have to unlearn your rejection of God and learn to love him again. Perhaps the real reason that many people do NOT focus on forgiving God, or looking at how they have framed God as evil, is because it would suggest tremendous guilt and fear, to admit that you have tried to attack and kill off God himself. Fortunately God has not held any of this against you and dispels it entirely, and is his hands are held open in welcome to receive you as his most loved creation once again.
To want to go towards your brothers in Christ, to want to forgive anything, you have to be willing to forgive God. You have accused him and must correct this. The world was made as an attack on God. You can forgive the world but you also have to forgive the idea that you've attacked God. You have made God into a false God and have redefined what you think God is like. This has to be corrected. You have to learn to love God again, and you can start by admitting that you don't.
"You who prefer specialness to sanity could not obtain it in your right minds. You were at peace until you asked for special favor, and God did not give it. For the request was alien to Him, and you could not ask this of a Father who truly loved His Son. Therefore, you made of Him an UNloving father, demanding of Him what only such a father COULD give. And the peace of God's Son was shattered, for he no longer understood his Father. He feared what he had made, but still more did he fear his REAL Father, having attacked his glorious equality WITH Him."
"Allegiance to the denial of God is the ego's religion. The god of sickness obviously demands the denial of health, because health is in direct opposition to its own survival."
"The "attack on God" made His Son think he was fatherless, and out of his depression he made the god of depression."
"Do not look to the god of sickness for healing, but only to the God of love, for healing is the acknowledgment of Him."
"The god of the crucifixion demands that he crucify, and his worshippers obey."
"You MADE the god of sickness, and BY making him, you made yourself ABLE to hear him. But you did NOT create him, because he is NOT the Will of the Father. He is therefore not eternal, and will be UNmade for you, the instant you signify your willingness to accept ONLY the eternal."
"You were willing to accept even death to deny your Father."
"You have interpreted the separation as a means which you have made for BREAKING your communication with your Father."
"You can give up the god of sickness for your brothers; in fact, you would HAVE to do so, if you give him up for yourself. For if you see him anywhere, YOU are accepting him."
"GOD is not at war with the god of sickness which you made, but YOU are. He is the symbol of willing AGAINST God, and you are afraid of him BECAUSE he cannot be reconciled with God's will. If you ATTACK him, you will make him real to you. But if you refuse to worship him, in whatever form he may appear to you, and wherever you think you see him, he will disappear into the nothingness out of which he was made."
"Embodiment of fear, the host of sin, god of the guilty and the lord of all illusions and deceptions, does the thought of death seem mighty. For it seems to hold all living things within its withered hand; all hopes and wishes in its blighting grasp; all goals perceived but in its sightless eyes. The frail, the helpless and the sick bow down before its image, thinking it alone is real, inevitable, worthy of their trust. For it alone will surely come."
"There is either a god of fear or One of Love."
"Or will you make another idol to replace it? For the god of cruelty takes many forms."
"The ego is not a traitor to God to Whom treachery is impossible. But it IS a traitor TO YOU who believe you have been treacherous to your Father." "You who have played that you are lost to hope, abandoned by your Father, left alone in terror in a fearful world made mad by sin and guilt, be happy now. That game is over."
