1 Corinthians 6:2-4

Do you not know that the saints (God’s people) will [one day] judge the world? If the world is to be judged by you, are you not competent to try trivial (insignificant, petty) cases? Do you not know that we [believers] will judge angels? How much more then [as to] matters of this life? So if you have lawsuits dealing with matters of this life, are you appointing those as judges [to hear disputes] who are of no account in the church?
