Who do you think put the atoms here that make up the bodies of the doctors and nurses? Who do you think created the space and allowed the time in which all of these things play out?
The part of God that is in within each of us is capable of a great many miraculous things, including healing. Work and effort are no part of that.
What is sad is that doctors and nurses sometimes do things that are harmful, rather than helpful. They have been taught, for instance, by the pharmaceutical giants and the schools they fund, that chemo and radiation are good for "curing" cancer, when in fact they are poisons that can lead to more cancer. The love and compassion of the doctor or nurse are far more powerful than any physical action they take. Those same pharma companies have participated in outlawing actual cancer cures. Some doctors are finally becoming aware of this, but the news media is part of the same corporate machine that jealously guards their profit engine.
In many cases, the faith of the patient is insufficient to perform the healing, so they rely on the mechanical of continuity-based reality. But there are instances when the mechanical damage is too much and no amount of physical effort can cure the injury or disease. That's when faith and the power of creation come into play. When the patient walks out of the hospital whole, days or weeks later, the doctors and nurses are amazed. Little that they did had anything to do with the miracle they observe.
When a patient places their faith in the mechanical, then they can only receive mechanical possibilities (surgery, chemicals, radiation, etc). But when a patient puts their faith in the source of all things, then the possibilities are infinite.
And some people do not know how to pray. If they "believe" in God, but remain fearful when they "pray," they will receive the object of that fear -- prolonged illness or death. But if they feel perfect peace and confidence when they ask God for a healthy body, the potential of which is vibrating within them, they will receive health -- and disease doesn't stand a chance.
