1 Corinthians 6:1-8 (ESV)

¹ When one of you has a grievance against another, does he dare go to law before the unrighteous instead of the saints? 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 incompetent to try trivial cases? ³ Do you not know that we are to judge angels? How much more, then, matters pertaining to this life! ⁴ So if you have such cases, why do you lay them before those who have no standing in the church? ⁵ I say this to your shame. Can it be that there is no one among you wise enough to settle a dispute between the brothers, ⁶ but brother goes to law against brother, and that before unbelievers? ⁷ To have lawsuits at all with one another is already a defeat for you. Why not rather suffer wrong? Why not rather be defrauded? ⁸ But you yourselves wrong and defraud—even your own brothers!
