"Thus is Christ's strength invited to prevail, replacing all your weakness with the strength that comes from God, and that can never fail. And thus are miracles as natural as fear and agony appeared to be before the choice for holiness was made."
"God is my strength."
This is a relatively "new" idea to me and perhaps to others. But this is a very powerful and significant component not only of miracle working but of fulfilling your function as a powerful Son of God.
There is a strength in you. The strength of Christ - the strength of the Holy Spirit - the strength of God. God put this strength IN you by giving it TO you in your creation. You HOST His strength. Therefore, what seems to be YOUR strength, is actually HIS strength. HE makes you strong. HE gives you power!
Whenever you attempt to do anything based on your OWN strength, you really are depending on littleness and weakness. And this little weakness is NOT very strong. It has not much power in it and is not very capable. Depending on your own strength makes you AFRAID, because your own strength is tiny and insufficient and not really capable of doing or dealign with much at all.
As you are developing trust, putting aside your authority problem, and coming to DEPEND ON God, opening up to the fact that God is in you, at your inner altar, and as you progress through the lessons etc, you'll encounter this idea that God is your strength. And that Christ lends you His strength. And it is their strength that makes miracles possible through you.
When you are trying to be a miracle worker, if you look at it like you're the one who has to muster the strength, courage, power, to accomplish a miracle, and you're going to have to be very brave and strong in order to "make something happen", not much is going to happen. Because really this is a state of fear and an attempt to be brave in the face of insurmountable difficulty and weakness.
A key element in miracle working has to be that you have opened up to recognize and allow and invite the power of God to be in you. Which means making room for the power of God/Holy Spirit/Christ IN you, to BE strong FOR you. To be your strength. Rather than relying on your own strength. Their strength is OFF THE CHARTS unlimited power. And it is their strength that gives miracles their unlimited power.
So your function isn't to be "strong on your own" or some kind of super hero. The hero is always attempting to be an amazing miracle worker with super powers. But really to ACTUALLY perform miracles you need to depend on the strength of God and allow HIM to have the strength to accomplish the task. He is the one who will supply your strength and make YOU strong. Without Him you are too weak to give anything or accomplish consistent healing.
So this idea that your strength is given you by God, that God SUPPORTS you, strengthens you, makes you powerful, but not OF yourself, is key in both miracle working and awakening.
