How We Talk is Dangerous

James 3:5-7

See how great a forest is set aflame by such a small fire! 6 And the tongue is a fire, the very world of iniquity; the tongue is set among our members as that which defiles the entire body, and sets on fire the course of our life, and is set on fire by hell.
NASU

Action: Can what we say and how we say it endanger our souls? How?
