Most Christian fundamentalists will talk about miracles, healing and supernatural events, I did when I was in that camp.
3 months ago my life partner Chris was diagnosed with breast cancer, its in her family 7 of them have died of it in the past 40 years, so you can imagine the fear the came upon us all. Tests were done biopsy, more tests, 100% confirmed. A date was given for surgery 19th March. at the beginning of March she went to a healing meeting in town where several people gathered around her and prayed, I was there, nothing visible happened. She felt all along that she wouldn't need surgery. She decided to go back to the doctor for more test. 4 Doctors and a surgeon looked at the latest tests, NOTHING. all gone. She went back 5 days later for more tests, still nothing.
How we dont don't know all we know is it appears that something amazing has happened.
Never discount a positive attitude, with respect to physical (and mental) Health.
A "healing ceremony" can indeed have profound effects on mental health-- and thereby directly affect physical health.
The brain-body connections humans have is very strong, and anyone can find studies that show poor mental health can have drastic and negative effect on the body. The reverse, naturally, is also true.
My grandad was diagnosed with colon cancer-- and the doctors were so certain (from symptoms and other things-- this was well before MRI or other non-invasive diagnoses... crude X-ray was the State Of Art back then) ... so certain they scheduled surgery. Between diagnosis and surgery, several weeks pass-- my grandad spending that time in Hospital.
He loved to laugh. That was his legacy, in fact-- everyone who knew him? Always remarked on his quick wit, and his huge collection of jokes. He liked to laugh, and he loved helping other people to laugh.
The nurses would often find him, not in his room--but down the hall somewhere, cheering up someone else who was hurting.
When they opened him up? They found.. nothing. No cancer. So they closed him back up. He was proud of his belly-scar, and would tell you several jokes about it too.
My overly-belabored point?
Attitude is Everything.
I have no doubt at all, that your partner's healing ceremony had Deep Significance to you and your partner--
and such things can not be dismissed lightly.
Attitude.
It is gratifying to read of someone's success, in battling Cancer. Good on you and your Life Partner-- I hope for you both, that you experience many-many more years together.
If there be a god? I would think that such a being would not need to intervene directly, instead? The Tools To Heal Ourselves already exist, sometimes.
Alas, it's a Hit Or Miss Proposition-- too many people die anyway,
in spite of positivism.
As Mark Twain quipped more than once?
All the Evidence Is Not In.
