Yes I do have demonstrable evidence. The cancer was there and now its not. Doctors I trust can verify that the cancer is not there anymore.
You must not read my posts very carefully. I asked you for demonstrable evidence of the "God" causing the cancer to go away,
not of the cancer going away. If I wake up in the morning and my car is missing I could say Santa Claus stole it, but there would need to be actual demonstrable evidence of such a claim. That is what you need to present.
Answer the question honestly: Do you believe (as true and actual) the claims of all supernatural or extraordinary claims that you hear on the basis of hear-say alone? Yes, as long as they don't impact me.
That's not what I asked you. I asked you if you actually believe
all claims to the supernatural by anyone with beliefs which contradict your own. Whether such claims effect you or not is entirely irrelevant to the question.
Secondly, and I said this before, belief is not a choice. You cannot will yourself to actually believe that a pink flying elephant is in your room right now. You can say
you believe it, but that would not be genuine belief. In order to actually believe something one must be convinced by some means, either by sound reasons or unsound reasons.
