I heard about the guy who prayed while crossing the Grand Canyon on a wire, although I did not see it.
I don’t know much about this guy or his profession; however, I think it is a mistake to do an activity that is very dangerous and expect God to make harm impossible.
What if God is directing us not to do something?
So there has to be a balance, and we have to use all the usual means to minimize risk in any activity including prayer, learning and training, counsel of others, and sometimes walking away and not doing something that we don’t have the time or desire to train for properly.
I would love to learn to fly. However, I know my schedule at present would mean the training that I could devote to flying would make me a mediocre (at best) pilot. Thus, at least for now, I don’t pursue this.
The professional pilots I have known did the activity for as long as they could keep their hours up, and after that they walked away and did not do the activity at all.
And those of us who are getting older, sometimes have to stop doing activities that we don’t have the reflexes to do safely anymore.
