James 3:2-5

Indeed, we all make many mistakes. For if we could control our tongues, we would be perfect and could also control ourselves in every other way. We can make a large horse go wherever we want by means of a small bit in its mouth. And a small rudder makes a huge ship turn wherever the pilot chooses to go, even though the winds are strong. In the same way, the tongue is a small thing that makes grand speeches. But a tiny spark can set a great forest on fire.
