As much as we can believe – will be done unto us.
Suppose a brother is laboring under the idea of his being ‘black‘ as a limitation on his possibilities in life. His whole mindset is therefore – a picture of limitation.
Where is he placing himself in Mind? Is he not in essence saying: “I cannot have and enjoy good things?”
And you can be sure he is demonstrating that he ‘cannot have‘, or ‘cannot accomplish‘ on some level.
It may take some time to reshape the basis of his thought; but he must begin by saying, “I realize that because of this Infinite Thing that finds Its place abiding in me, I know that good is now mine – all good!”
There is no mental coercion in this. We do not ‘will’ things to be done; things are brought into being, not by will, but by the power of the self-assertive Truth.
How much can one demonstrate? Just what you can believe.
How much can we see, how much can we accept, how much can we find in our consciousness that is no longer repudiated by our own denials?
Whatever that is, That much we can have.
