Only you can limit your creative power, but God wills to release it. He no more wills you to deprive yourselves of YOUR creations than He wills to deprive Himself of His.
Do not withhold your gifts to the Sonship, or you withhold yourself from God. Selfishness is of the ego but self-fullness is of the Soul because that is how He created it. The Holy Spirit is the part of the mind that lies between the ego and the Soul, mediating between them ALWAYS IN FAVOR OF THE SOUL. To the ego this is partiality, and it therefore responds as if it were the part that is being sided AGAINST. To the Soul this is truth, because it knows its own fullness and cannot conceive of ANY part from which it is excluded. The soul KNOWS that the consciousness of all its brothers is included in its own, as IT is included in God. The power of the whole Sonship AND OF ITS CREATOR is therefore its OWN fullness, rendering its Creation and its creating equally whole and equal in perfection.
The ego cannot prevail against a totality which includes God, and any totality MUST include God. Everything He created is given ALL His power because it is part of Him and shares His Being WITH Him. Creating is the OPPOSITE of loss, as blessing is the opposite of sacrifice. Being MUST be extended. That is how it retains the knowledge of itSELF. The soul yearns to share ITS Being as ITS Creator did. Created BY sharing, its will is to create. It does NOT wish to CONTAIN God, but to EXTEND HIS BEING.
The extension of God's Being is the Soul's only function. ITS fullness cannot be contained any more than can the fullness of its Creator. Fullness IS extension. The ego's whole thought system BLOCKS extension, and therefore blocks YOUR ONLY FUNCTION. It therefore blocks your joy and THIS is why you perceive yourselves as unfulfilled. Unless you create, you ARE unfulfilled. But God does NOT know unfulfillment, and therefore you MUST create. YOU may not know your own creations, but this can no more interfere with their reality than your unawareness of your Soul can interfere with its being.
The Kingdom is forever extending, because it is in the Mind of God. YOU do not know your joy because you do not know your own self-fullness. Exclude ANY part of the Kingdom FROM yourself, and you are NOT whole. A split mind CANNOT perceive its fullness, and needs the miracle OF its wholeness to dawn upon it and heal it. This reawakens its wholeness IN it and restores it to the Kingdom because of its ACCEPTANCE of wholeness. The full appreciation of its self-fullness makes selfishness impossible, and extension inevitable. That is why there is perfect peace in the Kingdom. Every Soul IS fulfilling its function, and ONLY complete fulfillment IS peace.
Insanity APPEARS to add to reality, but no-one would claim that what it adds is true. Insanity is therefore the NON-extension of truth, which blocks joy because it blocks Creation and therefore blocks self-FULFILLMENT. The unfulfilled MUST be depressed, because their self-fullness is UNKNOWN to them. Your creations are protected FOR you because the Holy Spirit, Who is in your minds, knows of them, and can bring them INTO your awareness whenever you will let Him. They ARE there as part of your own being, because YOUR fulfillment INCLUDES them. The creations of every Son of God are yours, because every creation belongs to everyone, being created for the Sonship as a whole.
You have not failed to add to the inheritance of the Sons of God, and thus have not failed to secure it for yourselves. If it was the will of God to give it to you, He gave it forever. If it was His will that you have it forever, He gave you the means for keeping it, and YOU HAVE DONE SO. Disobeying God's will is meaningful only to the insane. In truth, it is impossible.
Your self-fullness is as boundless as God's. Like His, it extends forever and in perfect peace. Its radiance is so intense that it creates in perfect joy, and only the whole can be born of its wholeness. Be confident that you have never lost your identity and the extension which maintains it in wholeness and peace. Miracles are AN EXPRESSION OF THIS CONFIDENCE. They are reflections both of your own proper identification WITH your brothers, and of your own awareness that YOUR identification IS maintained by extension. The miracle is A LESSON IN TOTAL PERCEPTION. By including ANY part of totality in the lesson, you HAVE included the whole.
You have said that, when you write of the Kingdom and your own creations which belong to it, you are describing WHAT YOU DO NOT KNOW. This is true in a sense, but no more true than your failure to acknowledge the whole result of the ego's premises. The Kingdom is the result of premises, as much as this world is. You HAVE carried the ego's reasoning to its logical conclusion, which is TOTAL CONFUSION ABOUT EVERYTHING. But you do not really BELIEVE this, or you could not possibly maintain it. If you REALLY saw this result, you COULD not want it. The ONLY reason why you could possibly want ANY part of it is because YOU DO NOT SEE THE WHOLE OF IT.
You therefore ARE willing to look at the ego's premises but NOT at their logical outcome. Is it not possible that you have done the same thing with the premises of God? Your creations ARE the logical outcome of His premises. HIS thinking has established them FOR you. They are therefore THERE, EXACTLY where they belong. They belong to your mind, as part of your identification with HIS. But your state of mind and your recognition of WHAT IS IN YOUR MIND depends, at any given moment, on what you believe ABOUT your mind. Whatever these beliefs may be, they are the premises which will determine WHAT YOU ACCEPT INTO YOUR MINDS.
It is surely clear that you can both accept into your minds what is NOT really there, and DENY WHAT IS. Neither of these possibilities requires further elaboration, although both are clearly indefensible even if YOU elect to defend them. But the function which God Himself GAVE your minds through His you may DENY but you CANNOT prevent. They are the logical outcome of what you ARE. The ability to SEE a logical outcome depends on the WILLINGNESS TO SEE IT, but its TRUTH has nothing to do with your willingness at all. Truth is GOD's will. SHARE His Will, and you will share what He KNOWS. Deny His Will AS YOURS, and you are denying His Kingdom AND yours.
