James 3:1-2
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.
James 5:16
5:16 So confess your sins to one another and pray for one another so that you may be healed. The prayer of a righteous person has great effectiveness.
