Dare any one of you, having a matter against another, prosecute his suit before the unjust, and not before the saints?
Do ye not then know that the saints shall judge the world? and if the world is judged by you, are ye unworthy of [the] smallest judgments?
References for 1 Corinthians 6:2
Do ye not know that we shall judge angels? and not then matters of this life?
If then ye have judgments as to things of this life, set those [to judge] who are little esteemed in the assembly.
I speak to you [to put you] to shame. Thus there is not a wise person among you, not even one, who shall be able to decide between his brethren!
References for 1 Corinthians 6:5
