"Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell." (James 3:5-6)

In the movie, The Indian in the Cupboard, a young boy has a magic cupboard which transforms his plastic cowboys and Indians into real people who are three inches tall - actual people from a different era. His Indian friend, Little Bear, is an Iroquois warrior from the time of the French and Indian Wars. He's the good guy fighting on the side of the British. The little boy wants to help Little Bear fight his enemies, so he takes some modern-day army men, puts them in the cupboard, and brings them to life. He borrows their machine guns and grenade launchers, and gives them to the Indians to use. Then he sends Little Bear back to his time. Little Bear and company soon surround their enemy with a circle about fifty yards across, then open fire. The only trouble is they're used to bows and arrows that shoot short distances, not twentieth-century weapons. And some of them are killed by friendly fire. (From Jim Nicodem)

The tongue is similar to the above-mentioned weapons. We often underestimate its destructive capabilities.
