1 Corinthians 6:2-6

Or do you not know that the saints will judge the world? If the world is judged by you, are you not competent to form the smallest law courts?

Do you not know that we will judge angels? How much more matters of this life?

So if you have law courts dealing with matters of this life, do you appoint them as judges who are of no account in the church?

I say this to your shame. Is it so, that there is not among you anyone wise who will be able to decide between his brothers and sisters,

but brother goes to law with brother, and that before unbelievers?
