Re: If you are sick, you need to cast out the demons.

"This in turn causes one who is sick and not finding physical healing to wait on God or to look for inspiration from other sick people....especially those who seem to overcome greatly."

You say this as if there is something wrong with it? I thought it was good to wait on God. It sure says so in the bible:

Isaiah 40:31
but they who wait for the LORD shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.

Sounds awesome to me! I think I'm going to keep waiting on the Lord!

And what is wrong with finding inspiration from those afflicted? And I don't know if "finding inspiration" is quite the right description. I'd say it's more that I am comforted by them, which might sound even worse to you, I don't know?
I see them being comforted by God in the midst of their afflictions, and in turn, they comfort me in the midst of mine. And I want to share any comfort both they and God have given me with those who need comforting.
Is this a crazy concept? No, it's right here in the bible:

2 Corinthians 1:
3Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, 4who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. 5For as we share abundantly in Christ’s sufferings, so through Christ we share abundantly in comfort too. 6If we are afflicted, it is for your comfort and salvation; and if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer. 7Our hope for you is unshaken, for we know that as you share in our sufferings, you will also share in our comfort.

8For we do not want you to be ignorant, brothers, of the affliction we experienced in Asia. For we were so utterly burdened beyond our strength that we despaired of life itself. 9Indeed, we felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead. 10He delivered us from such a deadly peril, and he will deliver us. On him we have set our hope that he will deliver us again. 11You also must help us by prayer, so that many will give thanks on our behalf for the blessing granted us through the prayers of many.
