James 1:26

1:26 If someone thinks he is religious yet does not bridle his tongue, and so deceives his heart, his religion is futile.

James 3:1-10

The Power of the Tongue

3:1 Not many of you should become teachers, my brothers and sisters, because you know that we will be judged more strictly. 3:2 For we all stumble in many ways. If someone does not stumble in what he says, he is a perfect individual, able to control the entire body as well. 3:3 And if we put bits into the mouths of horses to get them to obey us, then we guide their entire bodies. 3:4 Look at ships too: Though they are so large and driven by harsh winds, they are steered by a tiny rudder wherever the pilot’s inclination directs. 3:5 So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze. 3:6 And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence – and is set on fire by hell.

3:7 For every kind of animal, bird, reptile, and sea creature is subdued and has been subdued by humankind. 3:8 But no human being can subdue the tongue; it is a restless evil, full of deadly poison. 3:9 With it we bless the Lord and Father, and with it we curse people made in God’s image. 3:10 From the same mouth come blessing and cursing. These things should not be so, my brothers and sisters.
