1 Corinthians 6:2-5

6:2 Or do you not know that the saints will judge the world? And if the world is to be judged by you, are you not competent to settle trivial suits? 6:3 Do you not know that we will judge angels? Why not ordinary matters! 6:4 So if you have ordinary lawsuits, do you appoint as judges those who have no standing in the church? 6:5 I say this to your shame! Is there no one among you wise enough to settle disputes between fellow Christians?
