James 3:3-6

A bit in the mouth of a horse controls the whole horse. A small rudder on a huge ship in the hands of a skilled captain sets a course in the face of the strongest winds. A word out of your mouth may seem of no account, but it can accomplish nearly anything—or destroy it! It only takes a spark, remember, to set off a forest fire. A careless or wrongly placed word out of your mouth can do that. By our speech we can ruin the world, turn harmony to chaos, throw mud on a reputation, send the whole world up in smoke and go up in smoke with it, smoke right from the pit of hell.
