"Dare any of you, having a matter against another, go to law before the unrighteous, and not before the saints? Do you not know that the saints will judge the world?... And if the world will be judged by you, are you unworthy to judge the smallest matters?... Do you not know that we shall judge angels?... How much more, things that pertain to this life?.. If then you have judgments concerning things pertaining to this life, do you appoint those who are least esteemed by the church to judge ? (1 Corinthians 6:1-5)
Many commands of God require the exercise of righteous judgment.
"But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us" (2 Thessalonians 3:6)
"Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple" (Romans 16:17,18)
"Do not judge according to appearance, but judge with righteous judgment." (John 7:24)
