—Ephesians 6:18 (NASB)
Astute observers of the pieces of “the full armor of God” listed by Paul  have noted that when compared to the Roman armor of the day, one item is conspicuously missing: the spear. The sword is for close-in fighting and was most commonly worn on the belt, ready to be pulled out when necessary. The spear was for keeping the enemy at a distance. It wasn’t actually “thrown” except in more desperate situations, but used more like a lance to keep the enemy from getting within arms length. I believe this is the inferred meaning of prayer, that it is the spear in our spiritual warfare arsenal.
