For the purposes of this video, I offer an analogy:
Alligators are to humans in a boat on a river what the devil and his minions are to humans in the Barque of Peter steering toward salvation. They can't get you if you're close to the Lord, are properly armed, and remain inside the boat. But heaven help him who loses his weapons of the spirit and ventures out of the boat into the water. Just listen to what Fr. Corapi says about that.
It's a potent reminder of why, after imploring the Lord for our spiritual safety, we should also remember to invoke the powerful intercession of the Blessed Virgin Mary and St. Michael the Archangel. After all, they know how to deal with the infernal "alligators" out there right now, just looking for someone to devour.
