James 3:2-4

2We all stumble in many ways. If anyone is never at fault in what he says, he is a perfect man, able to control his whole body.

3When we put bits into the mouths of horses to make them obey us, we can guide the whole animal. 4Consider ships as well. Although they are so large and are driven by strong winds, they are steered by a very small rudder wherever the pilot is inclined.
