Thematic Bible: What the saints shall judge

Does any of you who has a complaint against someone dare go to law before the unrighteous, and not before the saints? Or do you not know that the saints will judge the world?

So if you have cases pertaining to this life, do you select those who have no standing in the church to judge? I say this to your shame! Can it be that there is not one wise person among you who will be able to arbitrate between his brothers? Instead, brother goes to law against brother, and that before unbelievers! Therefore, it is already a total defeat for you that you have lawsuits against one another. Why not rather put up with injustice? Why not rather be cheated? Instead, you act unjustly and cheat-and this to brothers!
