Book 6.28

"If," argues our adversary, "my prayers had any efficacy, they would also have been efficacious to save him from danger." In the first place, I reply, the danger into which you wish me to fall is certain, the help which I should receive is uncertain. Or call them both certain; it is that which injures me that comes first. Besides, you understand the terms of your wish; I shall be tossed by the storm without being sure that I have a haven of rest at hand.

Think what torture it must have been to me, even if I receive your help, to have stood in need of it: if I escape safely, to have trembled for myself; if I be acquitted, to have had to plead my cause. To escape from fear, however great it may be, can never be so pleasant as to live in sound unassailable safety. Pray that you may return my kindnesses when I need their return, but do not pray that I may need them. You would have done what you prayed for, had it been in your power.
