"What God DOES know is that His communication channels are not open to Him, so that He cannot impart His joy and know that His Children are wholly joyous. This is an ongoing process, not in time, but in eternity. God's extending outward, though not His completeness, is blocked when the Sonship does not communicate with Him as one. So He thinks, "My Children sleep, and must be awakened."
Notice here that Jesus talks about how God has his own "completeness", which is not in any way affected by our choice to separate. His own being, his real identity, is unaffected.
However, his "going out", his extending, his loving, his radiating, his creating, is BLOCKED, when the sons of God do not communicate with Him fully. This is because the sons have their own freedom. God's inner completeness is "separate from" the individual souls.
His creating, his radiating, goes out FROM his inner completeness, to create souls, but his own completeness is not changed by this act. Therefore the sons "are not God" as such. You are not merely the effect of God, or "God's radiance". You are more than that. God has ADDED TO existence in creating you as a distinct entity, "outside of" his own completeness. (really inside, but).
So there is a difference between what God IS - his completeness - his inner being - contrasted against his radiance, extension or creation, which goes out FROM Him to create his children, heaven, angels, holy spirit etc. God is thus complete within himself regardless of what his creation gets up to, which is why he does not participate in the separation, nor get dragged into it by his creations.
The key here is that God is free, and God creates beings who are free.
