The Mind Of Illusion

God did not make this universe; the Sons of God (Christ) did. They had been given all the creative powers of the Father and wondered what it would be like to live in a universe of time and space that was separate from God and based upon duality rather than unity. The Course calls this a "mad idea".For the first time, Christ had an idea that was not shared by God and Christ knew it. He imagined what it would be like to be apart from his Creator. Forgetting to laugh about that silly idea, feeling guilty he experienced something new. Fear.
The first ego was created. The mind believes that it is completely on its own. God knows absolutely nothing about this since in nonduality there is only a constant unchangeable Love. Christ made this universe through the Big Bang, composed of billions of fragments to hide from the supposed wrath of a vengeful Father. The idea of duality could not be carried out in God's reality so we created a dream universe of illusion and entered it as if falling asleep and dreaming. The trouble was that we went into such a deep state of sleep that we had no awareness that we were dreaming so we accepted the universe of illusion as real and forgot that we had a true home in the Celestial Realm.
The Course says the story of Adam symbolized what happened to us Yet the Bible says that a deep sleep fell upon Adam, and nowhere is there a reference to his waking up. This created a barrier in communication between the Father and the Son so deep that God decided a correction was necessary. God's extension outward, though not His completeness, is blocked when the Sonship does not communicate with Him as one. So He thought, "My children are asleep and must be awakened." So God wanted to awaken His Sons.
But there was a major problem.
Whatever God places His attention on becomes as if it is real. If God entered the dream to redeem his Sons then the dream would become real to Him as well and he would also be trapped. There would be the risk of both the Father and the Son becoming eternally separated from their true home, eternally losing their identity.
To solve the problem and allow God to keep his attention focused on Reality He created a special agent, The Holy Spirit, that could be a bridge between the two states of existence. So God created the Holy Spirit, Who was God's answer to the separation. He has created the Holy Spirit as the Mediator between perception and knowledge. Without this link with God, perception would have replaced knowledge forever in your mind. With this link with God, the perception will become so changed and purified that it will lead to understanding. The Holy Spirit entered the collective sleeping mind of Christ. A first Christ was healed and woke up in Heaven. In other words, we are All split off as "part" of the One Christ Mind. The Course repeatedly asserts there can only be one Son. Unity can only create unity. Multiplicity cannot originate from Oneness. If all His creations are His Sons, everyone must be an integral part of the whole Sonship. The Sonship in its oneness transcends the sum of its parts. Therefore the term Sons of God is used by Jesus for convenience in addressing his students as they believe they are.
On the other hand, the Son of God is the term used to denote who we truly are as Christ, the Identity of Oneness we shall awaken to after our dream of multiplicity is undone.
