"Cowardice keeps us double minded- hesitating between the world and God. In this hesitation, there is no true faith- faith remains an opinion. We are never certain, because we never quite give in to the authority of an invisible God. This hesitation is the death of hope. We never let go of those visible supports which, we well know, must one day surely fail us. And this hesitation makes true prayer impossible- it never quite dares to ask for anything, or if it asks, it is so uncertain of being heard that in the very act of asking, it surreptitiously seeks by human prudence to construct a make-shift answer."
-Thomas Merton, Thoughts in Solitude
