The idea that you are totally equal to God, is what's called the Authority Problem. Actually it's also the idea of sin. Some who think their relationship with God is to be "one" with Him, and thus completely equal with Him, are not understanding that God came FIRST. Or that oneness does not actually mean "you are Him".
He is the creator of you, you are not the creator of Him. He created the Sonship and you were created to ADD TO the Sonship. But you cannot create God or cause God or add to God Himself. That makes you "below" Him in a sense, or as Jesus says in the course, "the Father is GREATER".
It is also appropriate to have AWE of God because He IS greater and above you, and not to have awe of your brothers who ARE your equals. God is GREATER because He is all encompassing, and you are within God, as a part of God, caused BY God, as one of His thoughts, and He therefore spans more than just your own soul.
The idea that being one with him means total equality completely ignores these dynamics and suggests you are as much the creator of God as he is of you. And that unfortunately is where the tiny mad idea began, where you as an effect of God attempted to be the cause of Him, and where the entire ego thought system started. His Kingdom also cannot increase at all if you are God's exact equal because you and God would be in a deadlocked power struggle.
You have to be a son, in order to set up the dynamic that "A Son of a Father must have a Son", establishing God's fatherhood and your sonhood. And being like the father you too become a father, thus co-creator with Him. But your co-creatorship does not allow you to co-create God Himself, and yet God Himself does create you.
And so you are not equal to God in all ways and functions, but you ARE like Him in terms of mirroring the ability to create, IN ADDITION TO what already has been created BY Him. The notion that you have equal creative function with God is to suggest you are capable of creating yourself, and that is what the ego believes is true.
You can add your creations to His Kingdom, but you cannot overthrow the Kingdom itself. Nor can you attack or destroy what HE already created, that being yourself, your brothers, the Holy Spirit, and the angels. All of this "state of the union" is somewhat more elaborate than simply to say that "it's all just oneness", and it certainly is not compatible with an idea of non-duality which implies "no sons at all."
God has a family, and you are part of it. God is a creator with many creations and those creations have many creations and all of them co-create together. This is what A Course in Miracles teaches, not that we're all going to just dissolve into nothing, with no self and no creative function. God has established you as a free-willed co-creator forever.
In fact, if you weren't a SON of God and not God's equal, you would have INHERITED NOTHING, and would never be a HOST to God Himself. God GAVE you everything He had in your creation, thus extending His Self to you, sharing His will and mind and power, and establishing you as SHARER of his being. Because God is your father, you have an inheritance which is waiting for you to reclaim it.
"The world, in its original connotation, included both the proper creation of man by God, AND the proper creation by man in his Right Mind. The latter required the endowment of man by God with free will, because all loving creation is freely given."
"Think not He wills to bind you, Who has made you co-creator of the universe along with Him. He would but keep your will forever and forever limitless."
"My mind holds only what I think with God. That is a fact, and represents the truth of What you are and What your Father is. It is this thought by which the Father gave creation to the Son, establishing the Son as co-creator with Himself."
"Revelation is NOT reciprocal. It is always FROM God TO man (souls). This is because God and man are NOT equal. "
"This appears to contradict another statement: "I and my Father are one." It doesn't. There are still separate parts in the statement, in recognition of the fact that the Father is GREATER."
"The creative power of both God AND His Creations is limitless, but it is NOT in reciprocal relationship. You DO communicate fully WITH God, as He does with YOU. This is an ongoing process in which you SHARE, and BECAUSE you share it, you are inspired to create LIKE God. But in Creation you are NOT in a reciprocal relation TO God, because He created YOU, but you did NOT create Him. We have already stated that only in this respect your creative power differs from His."
"I have repeatedly emphasized that awe is not appropriate in connection with me (Jesus), BECAUSE of our inherent equality."
"The word "Awe" should be reserved only for revelations, to which it is perfectly and correctly applicable. It is NOT appropriately applied to miracles, because a state of true awe is worshipful. It implies that one of a lesser order stands before the Greater One. This is the case only when a Soul stands before his Creator. Souls are perfect creations, and should be struck with awe in the presence of the Creator of Perfection."
"Equals cannot be in awe of each other, because awe ALWAYS implies inequality. Awe is not properly experienced even to me (awe of Jesus). That is why in that short introductory vision, I knelt beside you, FACING the light."
"Your creations are your gift to the Holy Trinity, created in gratitude for your creation. They do not leave you, any more than you have left your Creator."
"He (God) does nothing last, because He created first and for always. It must be understood that the word "first" as applied to Him is not a time concept. He is first in the sense that He is the First in the Holy Trinity Itself. He is the Prime Creator, because He created His co-creators. Because He did, time applies neither to Him nor to what He created. The "last step" that God will take was therefore true in the beginning, is true now, and will be true forever. What is timeless is always there, because its being is eternally changeless."
