Sorry would love to " demonstrate a Gods action" if I could but you wouldn't be able to see me. And since I cant use words, your stuck....Faith is just what it is Faith, you either have it of you don't. I chose to have it and it helps me through some very rough times.
I understand you clearly,... life is tough, people use what works.
Faith and belief is part of emotions, feelings,..you can believe just about anything, like santa claus.
