Virtue has great strength, but vice makes no benefit.

See how Peter slept and was not in anguish or fear. In the very night when he was about to be brought before the kids sleepcourt he slept, leaving everything to God. Indeed the multitude becomes powerful when virtue is present. And it had such a power that even though the doors were closed, chains bound the apostle and the jailers slept at both his sides, virtue delivered him and saved him from all those difficulties. So if virtue is present the multitude has great strength, but if vice is present it makes no benefit.
