You get a diagnosis followed by a prognosis. This comes from one you respect, and so you believe it. Is not the other human, just as you are? You put your full faith in them because you see and hear them. They have a special education. You may not. Regardless, regard them not as God. Yes, you are all facets of God, but whilst wearing your human suits you can and oft do have Self-limiting thoughts. Has the one making the diagnosis and providing the prognosis tuned in to Spirit? Have you? Have you any idea how powerful is this aspect of yourself? This aspect of yourself never ails and never fails.
If you were able to set aside your human beliefs, you would not ail at all. Fully knowing yourself as a spirit-being, you can create so-called miracles. Be wary of the pronouncement of humans who do not know the truths of the Spirit. Work in concert with Spirit to cure all ills.
