To prove faith, you must surrender to its challenge.
You must grab hold of its promise (something you can’t physically see) on faith’s own terms. Otherwise, you cannot claim to have given faith and honest try.
By nature, faith only works by letting go of your doubts, and grabbing hold of something else.
Once you’ve done so, it’s too late to turn back. You have already believed.
Isn’t faith tricky?
Isn’t faith fun!
