In God, who is cause, He created Christ, who is Effect. Or "Father" created "Son".
At the "separation", the Son attempted to separate from the Father, thereby introducing a separation between Cause and Effect.
Cause and Effect in Heaven are ONE, unified and completely immediately intertwined. But after separation, a "distance" or "gap" arose (illusion of course) between them, suggesting that Cause had been robbed of its ability to produce effects, and that the effects had not been caused by God.
Essentially this means two things. It means God seemed then to not create the Son, making an illusion that God’s will has been stopped (ie the Son has power over God). And then additionally, that the Son has no Father and therefore has to INVENT a false God as a substitute.
What also then happens is, now that there’s a gap between cause and effect, it *seems* as though somehow the "effects" coming from a cause are separated off from the cause. Instead of them being One, they are cut off from each other.
This sets up the entire ego thought system which believes and perceives that you can cause something WITHOUT experiencing the effects. And this further leads to the belief that an external cause (aka God, turned into an evil God) can do things to make you an effect against your will.
The more that your belief in separation between cause and effect increases, the more you become an unconscious victim, aka dead. It heightens your false perception that "causes outside of you" are producing effects inside of you. This makes you suffer and makes you a victim in every way.
If you are "heavily steeped in ego", strongly projecting sin (cause), and are believing that stuff applies to others that does not apply to you or vice versa, or that you can cause effects in others without those effects being in you and vice versa, then you have belief that Cause (Father) is separate from Effect (Son). To the degree that you believe this, you will experience an intensified sense of *separation*, denial, disassociation, war, and unconsciousness.
As we apply forgiveness, we undo the belief in separation by recognizing that what we thought applied "separately" to others but not to ourselves, is actually our attitude about ourselves. What we thought was their own separate sin, is actually our own sin. What we thought happened against our will, must have been caused by ourselves. It also means learning that you cannot be affected by anyone or anything other than yourself, or against your will, in any way!
When finally cause and effect are reunited, Father and Son are reunited, mind becomes ONE and whole, what applies within applies without, what applies to you applies to the entire Sonship, your innocence is everyone’s innocence, you will see your Self in everyone, and you will know sanity again. It is the end of war. It is peace, and the final release from all forms of self-attack which were masquerading as attack by separate causes. It is the end of death.
