The tongue also is a fire, a world of evil among the parts of the body.  It corrupts the whole person, sets the whole course of his life on fire, and is itself set on fire by hell.  

                               (James 3:6) 

James compares the damage the tongue can do to a raging fire.  The tongue can do terrible damage.  Satan uses the tongue to divide people and put them against one another.  Idle and hateful words are damaging because they spread destruction quickly, and no one can stop the results once they are spoken.  A few words spoken in anger can destroy a relationship that took years to build.  Before you speak, remember that words are like fire-you can neither control nor reserve the damage they can do.
