I can go along with you on this.
I was at a fellowship (long past my TWI days, but it was reformed ex-Wayfers who'd walked away from TWI doctrines). This was 20 years ago, I don't remember all the details.
An older man attended. He had walked with sticks or crutches or some such (not in a wheelchair) for many years - the fellowship leader took him quietly aside into the kitchen with 1 or 2 other witnesses, prayed with him and held his hands as he took his first steps. A great shout of joy alerted all the rest of us to something amazing. Here was this man, walking, unaided, stumbling about in the kitchen. He then went outside (accompanied for safety by a couple of people) and spent an hour or more just walking around the little quiet road in which this fellowship took place, and getting better and better at balance, and walking. He was crying with joy.
I don't know about afterwards, as I didn't go there often. I saw this. It happened.
Who got the glory? God. The leader backed off and claimed no credit at all.
