"Indeed, we put bits in horses’ mouths that they may obey us, and we turn their whole body. Look also at ships: although they are so large and are driven by fierce winds, they are turned by a very small rudder wherever the pilot desires. Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! And the tongue is a fire, a world of iniquity. The tongue is so set
among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell." James 3:3-7
One of the toughest things we can ever do is to allow God to be in control of our words...but it is also the safest.
