Of the great safety of being humble.
St. Antony tells how once in a vision he beheld all the snares of the evil one spread over the whole earth. When he looked upon them and considered their innumerable multitude, he sighed, and said within himself, "Who is able to pass safely through such a world as this?" Then he heard a voice, which answered him, "The humble man alone can pass safely through, O Antony. In no way can the proud do so."
