In ACIM there are lessons surrounding the idea that God is my strength. It's a very simple 4-word sentence. But in it you can also see the dynamic of relationship between you and God, in terms of the power that you have.
Specifically, MY strength, IS GOD, AND is myself.
Which means, that within you, there is a strength, which you experience as YOUR strength. But, at the same time, this strength that is in you, could be said to BE God himself. It is not one or the other, it is both.
This is because of the chain of cause effect that happens in creation and extension. When God creates a child he doesn't just deposit a new thing in an environment. He doesn't walk away and leave it alone. He doesn't disconnect from it unbilically.
Instead, He extends himself out and shares himself, RETAINING his thought in his mind, keeping his creation WITHIN his being, and the two are one, shared. Which means that God does not let you go, or disconnect from you, and you effectively don't leave the womb.
Therefore you kind of have God embedded in you still.
Therefore, anything you have, is indeed truly YOURS, because it is fully given to you and fully shared without conditions. But at the same time, it is fully GOD's, because he gives it to you not by losing it but by SHARING it. You overlap and share the same space, and everything there belongs to both of you.
So now the strength you have in you is yours, AND it is God's. The power that is in you, which makes you ALL POWERFUL, is God's power.
It is also not appropriate to suggest that the power that is in you is ONLY God's power. Nor that ONLY God wields that power. Or that only God does anything. This is the flipside of further ego thinking that God and you are separate.
The power that is in you is indeed HIS power, and He is all powerful, as well. But this power IS also yours. And his. At the same time. Together you SHARE the same power.
Power MUST be shared to BE power. It does not belong ONLY to you. But this also doesn't mean it DOESN'T belong to you, ONLY to God.
God has given it to you fully to use AS YOUR OWN, and freely. But only provided that you use it WITH everyone AS everyone. Everyone has the same power because everyone was created BY and WITH power.
It's tricky to understand because our mind wants to separate things off and assign ownership to one and not another. Our power is God's AND ours. We as children of God ARE all powerful. There is nothing WE cannot do. We do it WITH GOD. We AND God are all powerful.
But without God, if you take God out of it, you end up with NO power, because HE has all power. Without him you have NO power. With him, you BOTH have power. Without God you have nothing. With God you have everything.
God AND Christ are all-powerful. Jesus acknowledged God as the source of his own power, giving God FULL credit for the power, because he knew the power did not COME FROM himself. But this did NOT mean that Jesus had NO power, because he had inherited ALL power from God, and so WAS and IS extremely powerful.
"I am not helpless but all powerful."
"YOU did not make this power any more than I did. It was created to BE shared, and therefore cannot be meaningfully perceived as BELONGING to anyone AT THE EXPENSE of another. "
"My Father gives all power unto me"
"Your Will can do all things in me, and then extend to all the world as well through me. There is no limit on Your will. And so all power has been given to Your Son."
"You are part of Him who IS all power and glory, and are therefore as unlimited as He is."
"God has one Son, and he is the resurrection and the life. His will is done because all power is given him in Heaven and on earth."
"To say, "Of myself I can do nothing" is to gain all power. And yet it is but a seeming paradox. As God created you, you have all power."
"All power in Heaven and earth is therefore given him and he will share it with you when you have completed yours."
"By teaching the power of the Kingdom of God Himself, He teaches you that ALL POWER IS YOURS."
"All power is given you in earth and Heaven. There is nothing that you cannot do."
"Knowledge is power, and all power is of God. You who have tried to keep power for yourselves, have lost it. You still HAVE the power, but you have interposed so much between it and your AWARENESS of it, that you cannot use it."
"He understands all power in earth and Heaven belongs to him because of who he is."
"They will always be treasured by God, because they belong to His Beloved Sons who belong to Him. All power and glory are yours because the Kingdom is His."
"My mind will always be like yours, because we were created as equals. It was only my DECISION that gave me all power in Heaven and earth."
"But the truth is very simple; ALL POWER IS OF GOD. What is NOT of Him has no power to do ANYTHING."
"Sickness is idolatry, because it is the belief that POWER CAN BE TAKEN FROM YOU. But this is impossible, because you are part of God, Who IS all power."
