Must it? Here's why not
So, this man tested god. How do you do that? How does he have a serious illness of any kind without doctors treating him for it? How would he know he had a serious illness? How do you go get your blood tested for anything unless you are sent to a clinic? Without doctors being involved the clinic would think he was crazy. I would agree with the clinic.
Yes, I had a serious illness and I got better so there must be a creator and I know now that he likes me. ROTFLMAO here.
