38 Thus David failed not, for he was dear to all, and wished to be loved rather than feared by his subjects. Fear keeps the watch of temporal protection, but knows not how to keep guard permanently. And so where fear has departed, boldness often creeps in; for fear does not force confidence but affection calls it forth.
39. Love, then, is the first thing to give us a recommendation. It is a good thing therefore to have our witness in the love of many. Then arises confidence, so that even strangers are not afraid to trust themselves to your kindness, when they see you so dear to many. So likewise one goes through confidence to love, so that he who has shown good faith to one or two has an influence as it were on the minds of all, and wins the good-will of all.
