Everything about this world points in the direction of death. "All its roads but lead to disappointment, nothingness and death." It was designed to do so. Our job as beings from another world, is to demonstrate that we are not under any of these laws, all of them can be broken, and that it is possible to reconfigure the body to symbolize eternal life here in the dream. A body that shows health and vitality and life, has no scars, has no damage, is perfectly functioning, rejuvenated by the Holy Spirit, and filled with what we'll call "life". Its condition must be completely under the "control" of the mind, requiring not a single belief that there are any other external separate causes of sickness or death.
To overcome death, death MUST be a choice. And the only way to surmount death must entail the ability to choose not to produce death. To choose not to die physically. It has to be possible for the mind to have power over and be stronger than not only the body but all supposed external worldly causes, otherwise the belief remains that something "out there" can come along with an alien will and decide for you against your will that the body should die. The secret of salvation tells us we do EVERYTHING to ourselves, and therefore have the power, should we so choose, to simply choose NOT TO "do death".
The body has to respond, it has no will of its own, no decision of its own, and is ONLY an effect of the mind, not the world. It must line up and obey and correspond to mental health. The belief that the body has its own choice/mind/power to make itself sick or well, or that the world can do the same, IS the belief in death ie the belief in an external separate power that can choose FOR you (the dream choosing for you) that you shall be affected and powerless to stop it. A child of God could never be in a position to be powerless to stop such an attempted attack. God does not will that we be in a position where something can ever happen that we do not ask for. "My self is ruler of the universe" ... "nothing comes to me unbidden by myself" .... "what I want to happen I receive" .... "what I do not want does not occur" etc.
It's a position of tremendous empowerment and causality. Mastery over the world, the body, sickness and death. A living demonstration of life and holiness - wholeness, which is health. Taking a hold of a body of this world, from a vantage point of another world, with a power not of this world, and using it as a tool, a window, through which the light of heaven can extend and shine with healing and love into this world, causing this bodily figure to be animated like a puppet via supernatural power that breaks and defies all the laws of the world. Spirit is in charge, not the dream world. The primary laws of the Kingdom overthrow the secondary laws of spacetime. All laws of physics can be broken by the Spirit. "There is nothing my holiness cannot do." "What the holy spirit enables you to do is clearly not of this world."
Death ultimately is learned to be not even a threat, not even a thing, not even a possibility, to one who recognizes that the only way to die is to choose to do so. "You cannot die unless you choose to do so." "No one dies without their own consent" "You cannot be hurt unless you hurt yourself." Ultimately the teaching is that we are IMMORTAL, invulnerable, unassailable, invincible, unlimited beings. Any testifying of any other kind can only result when we, ourselves, consent to misuse our free will to weave what must be lies and illusions and fictions, trying to prove that we are not immortal. "Sickness is an attempt to prove you can be hurt." You cannot be hurt if you are immortal.
The body is used by a twisted mind to pretend it is not immortal, to put on a show and to try to convince itself and others that it can die. It cannot. "You are immortal and you cannot die." When we recognize the futility and pointlessness of trying to die when we never can, we'll stop MAKING it happen, and will simply choose to live eternally. The supernatural power of God will protect us and make sickness and death impossible. Nothing can happen against our will. Not even death. There are no "accidents" or "environmental influences" or "acts of nature" or "just old age" creeping in like some kind of unwanted invader. There is only our own mind and what it is doing to itself. When it chooses never again to die, it will make death impossible and raise the dead. "Swear not to die you holy son of God, you've made a bargain that you cannot keep" .... you cannot die, you cannot succeed at it, it does not work, you carry on. You already have eternal life.
