St. Joseph the Hesychast: Who has conquered the devil?

Who has conquered the devil? He who knows his own weaknesses, passions, and shortcomings. Whoever is afraid of knowing himself remains far from knowledge, and he doesn't love anything else except seeing faults in others and judging them. He doesn't see gifts in other people, but only shortcomings. And he doesn't see his own shortcomings, but only his gifts. This is truly the sickness that plagues us men of the eighth millenium (Ps 24:18, LXX): we fail to recognize one another's gifts.
