Above all, [take] the shield of faith with which you will be able to quench all the fiery darts of the wicked one.  -Ephesians 6:16

While visiting a museum, I was intrigued by a small inscription describing a class of Roman gladiators-the Retiarii-who fought using only a net and a trident. Of all the fearsome and lethal weapons available to those warriors, who often battled to the death, these men were given two items-a piece of webbing and a three-pronged spear. When they entered the arena, their survival depended on how well they used their weapons.
