The ego produced the idea that when you cause something, it produces an effect, but the effect itself is not CAPABLE of causing something in turn.
This shows up in the relationship between mind and matter or mind and body. The body seems to be an "end result" but of itself it cannot create anything. The ego made the illusion that it can create children but really it is a dead end.
This is because the ego "separated" cause and effect, meaning that mind seemed to become cause and matter became effect, so that mind would seem to STOP being able to CREATE something that in turn can create.
When you think about your self in heaven, you are an effect of God. But in God's world cause and effect are not split apart like this, and an "effect" is NOT a dead end. When God creates something, he give it ALL of his own ability to create, and therefore it ALSO becomes a CAUSE.
You are an effect of God, which means you are still as God created you, but it DOES NOT MEAN that you therefore have to be whatever God forces you to be. You are not like the "body of God" or some kind of projection of Him that cannot think for itself or has no will of its own.
This is a very important point because in terms of the ego's thinking, if you are just an EFFECT, then you cannot CAUSE anything, and that basically means God created death, or created an end to extension.
You are created TO EXTEND, to CO-CREATE, and to CAUSE CREATION. You are an effect of God but you are ALSO FREE to cause of your own free will. If you were not given the freedom to be a cause, you could not be like God or in his likeness, and you would not be able to create like Him.
So God has created you, you are the effect of Him, but you are also a cause. God causes causes. God creates creators. And because you ARE a creator and you can create, you MUST HAVE freedom to WILL freely. Your independent free will was given you BECAUSE IT WAS NECESSARY in order to grant you the ability to create freely.
By God having created creators who can create creators, and IF those creations freely willingly choose to extend or "will like God's will", then creation extends endlessly as a continuous outflowing of creativity. When a creation of God freely chooses to dream and to pretend to oppose God's "intention" and tries to block their own free will, his "communication channels" are blocked and God thus recognizes his son is "sleeping" and creates the Holy Spirit to help him to FREELY CHOOSE whether/when to wake up.
