We would hope to take over His duty of punishing us, by punishing ourselves in suffering and martyrdom so much that He might actually pass us by.
We tell ourselves, if we suffer enough and really put on a good show for how much we should suffer, then God might take 'pity' on us and, while laughing at ourpatheticness, decide to pass us by as being 'not worth the effort'.
Sickness is a defense against the truth, and this kind of behavior is a defense mechanism to try to defend ourselves from God.
We would worship sickness as an idol, by making sure that we suffer in silence. We would prefer to do it in isolation, and especially keep it hidden so that nobody knows about it.
We would also keep away from us all loved ones and friends and anyone who might offer signs of 'love' or 'joining' because those are outlawed when sickness is being worshipped.
Also when a person is in sickness, sickness will itself become 'all powerful' and overthrow all other rules and demand that it be obeyed and worshipped and give a special 'free pass' to get away with anything. All other normal modes of interaction are off and nothing that might bring healing is allowed in.
A fortress is erected around sickness to protect it and to keep it in the dark, just in case anyone might realize that it has no foundation or who might strip it of its false decorations. Only in the dark, behind closed doors, secretly suffered, can it maintain a sense of power or torture or truth.
Expose sickness to the light and it's crumbles and withers and disappears. Light, love, sharing, joining, oneness, all are antidotes for sickness. Openness and a willingness to reveal sick ideas of separation and punishment to the One Who Is Open (God) is sure to shine a healing light. And that is what the sick person does not want.
Lives of quiet desperation. Suffering in silence. Taking a hit for the team. Being the martyr who carries all the burden. Being the whipping boy or the one who keeps everything afloat, leeched off by everyone else. The poor sucker who gets to suffer in the dark, alone and quiet and abandoned. All of these are identities and roles that arise in the worship of sickness, put on the altar as an offering to the God of Death. Which, by the way, does not exist.
The ego's God is the God of sickness and punishment. The real God could not conceive of such things. The real God has no concept of sickness in Him, knowing it is forever impossible to separate from Himself or not be completely joined with His creation.
In truth there is no sickness and there is no death. All of the rest is just denial, a pretend play at acting as if you should suffer for some good reason. There is no good reason. There is no justification for separation because it is impossible.
You are not sick, you are just playing dead.
God still loves you.
