"You never know how much you really believe anything until its truth or falsehood becomes a matter of life and death to you.
It is easy to say you believe a rope to be strong and sound
as long as you are merely using it to cord a box.
But suppose you had to hang by a rope over the precipice.
Wouldn't you then first discover how much you really trusted it?
....Only a real risk tests the reality of a belief."
C. S. Lewis.
