Suppose one of you wants to bring a charge against another believer. Should you take it to the ungodly to be judged? Why not take it to God's people?
References for 1 Corinthians 6:1
Don't you know that God's people will judge the world? And if you are going to judge the world, aren't you able to judge small cases?
Don't you know that we will judge angels? Then we should be able to judge the things of this life even more!
So if you want to press charges in matters like that, appoint as judges members of the church who aren't very important!
I say this to shame you. Is it possible that no one among you is wise enough to judge matters between believers?
Instead, one believer goes to court against another. And this happens in front of unbelievers!
