“The mind can make the belief in separation very real and very fearful. And this belief is the devil. It is powerful, active, destructive, and clearly in opposition to God, because it literally denies His fatherhood. Never underestimate the power of this denial. Look at your life and see what the devil has made. But know that this making will surely dissolve in the light of truth, because its foundation is a lie.” (ACIM, COA ed., T-3.XI.9:1-6)
Now we know what the devil concept was all about. We know that it is really the egoic notion of things, lived out in separation from God. We could not truly separate from Him, because we are part of Him, but we could live, with the ego, as though we are separate. And therefore alone. And the ego is the symbol, as well as the essence, of fear. Thinking we are all alone in the universe will frighten the most courageous.
In the egoic world, we thought that if there were good, there had to be a counterbalancing of evil. Contrasts were the way that the drama proceeded. And there were so many dramas! We felt the height of joy, but just for a moment, before we were dashed down and in misery, despair. Is this any way to live?
We can’t live in this illusion any longer, because we know better now. As children of God, individuals within whom He dwells, our real will for ourselves is not a contradiction from His will for us. This truth can be hard to accept, for the separation has been long and cruel. The Holy Spirit will guide us gently to the truth that the wills are the same. How could they not be, when God is living through us?
God’s way is true reality; our parody of His creation has been and will always remain, illusion. Not being real, our illusion weaves fanciful imaginings that bring us down, and down, and down, repeatedly?
When will we ever learn?
MIRACLES EACH DAY 
People see light and darkness, experience physical life and death and ASSUME that good has to be balanced by evil. The construct of the devil, the ultimate example of which was Lucifer, who rebelled against God, somewhere in the Cosmos, very long ago, is indeed the ego of the created being.
Hi Celia,
I believed in the illusion of the ego most of my life.
My spirit is experiencing an awaking daily as I continue to die to self.
The Holy Spirit teaches only what is real and true.
He reconciled me back to God, others and Self.
Great post!😀
