Under Gods command

Satan uses the tongue to divide people and pit 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.  We dare not be carless with what we say thinking we can apologize later, because even if we do, the scars remain.  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 reverse the damage they can do.
