1 Corinthians 6:
1 Dare any of you, having a matter against another, go to law before the unjust, and not before the saints?
2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters?
3 Know ye not that we shall judge angels? how much more things that pertain to this life?
4 If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.
5 I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren?
6 But brother goeth to law with brother, and that before the unbelievers.
