1 Corinthians 6:1-8

Dare any of you, having a matter against his neighbour, go to law before the unrighteous, and not before the saints? Don’t you know that the saints will judge the world? And if the world is judged by you, are you unworthy to judge the smallest matters? Don’t you know that we will judge angels? How much more, things that pertain to this life? If then you have to judge things pertaining to this life, do you set them to judge who are of no account in the assembly? I say this to move you to shame. Isn’t there even one wise man amongst you who would be able to decide between his brothers? But brother goes to law with brother, and that before unbelievers! Therefore it is already altogether a defect in you that you have lawsuits one with another. Why not rather be wronged? Why not rather be defrauded? No, but you yourselves do wrong and defraud, and that against your brothers.
