Belief is not a merely intellectual process, belief is not a mere persuasion of the mind, belief is something that is in our heart, and what you believe, you must do, because belief is from God. It is to the heart that God speaks, it is in the heart that God resides.... Here is a work that you have undertaken, a work so gigantic, so stupendous, the means for which are so poor, the resistance to which will be so strong, so organised ... and what means have you with which to carry out this tremendous work of yours? If you look at it intellectually, it is hopeless.... This intellectual process, if it is used honestly, if it is followed to the very end, leads you to despair. It leads you to death.
