There seems to be a conflict of ideas about judging.
Jesus Christ says plainly that He judges no man.
Joh 8:15 You judge according to the flesh; I judge no one.
The very next verse seems to contradict His own words. Jesus Christ judges according to the Father, He does not judge on His own.
Joh 8:16 And yet if I do judge, My judgment is true; for I am not alone, but I am with the Father who sent Me.
Christ will show judgment to the gentiles.
Mat 12:18 "BEHOLD! MY SERVANT WHOM I HAVE CHOSEN, MY BELOVED IN WHOM MY SOUL IS WELL PLEASED! I WILL PUT MY SPIRIT UPON HIM, AND HE WILL DECLARE JUSTICE TO THE GENTILES.
Here’s the answer, plain and simple. Christ judges with His Father’s will in mind.
Joh 5:30 I can of Myself do nothing. As I hear, I judge; and My judgment is righteous, because I do not seek My own will but the will of the Father who sent Me.
The first verse I quoted explains itself. Christ judges no man after the flesh.
Paul made judgments. Notice carefully that Paul’s judgment was for the ultimate good of the fornicator.
1Co 5:1 It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles—that a man has his father's wife!
1Co 5:2 And you are puffed up, and have not rather mourned, that he who has done this deed might be taken away from among you.
1Co 5:3 For I indeed, as absent in body but present in spirit, have already judged (as though I were present) him who has so done this deed.
1Co 5:4 In the name of our Lord Jesus Christ, when you are gathered together, along with my spirit, with the power of our Lord Jesus Christ,
1Co 5:5 deliver such a one to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus.
Paul was upset because the church members could not judge small matters.
1Co 6:1 Dare any of you, having a matter against another, go to law before the unrighteous, and not before the saints?
1Co 6:2 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?
1Co 6:3 Do you not know that we shall judge angels? How much more, things that pertain to this life?
1Co 6:4 If then you have judgments concerning things pertaining to this life, do you appoint those who are least esteemed by the church to judge?
1Co 6:5 I say this to your shame. Is it so, that there is not a wise man among you, not even one, who will be able to judge between his brethren?
Christ said judge not, but it is clear that we are expected to judge. The following scriptures need to be read carefully. We need to get rid of our faults before we can judge faults in others. We should not be judgmental or condemning, but rather, we should be giving Christians.
Luk 6:37 "Judge not, and you shall not be judged. Condemn not, and you shall not be condemned. Forgive, and you will be forgiven.
Luk 6:38 Give, and it will be given to you: good measure, pressed down, shaken together, and running over will be put into your bosom. For with the same measure that you use, it will be measured back to you."
This verse backs up what our attitude should be.
Php 4:8 Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things.
Mat 7:1 "Judge not, that you be not judged.
Mat 7:2 For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you.
Mat 7:3 And why do you look at the speck in your brother's eye, but do not consider the plank in your own eye?
Mat 7:4 Or how can you say to your brother, 'Let me remove the speck from your eye'; and look, a plank is in your own eye?
Mat 7:5 Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother's eye.
Better to judge ourselves.
1Co 11:31 For if we would judge ourselves, we would not be judged.
1Co 11:32 But when we are judged, we are chastened by the Lord, that we may not be condemned with the world.
Daniel was much loved; because he chastened himself.
Dan 10:11 And he said to me, "O Daniel, man greatly beloved, understand the words that I speak to you, and stand upright, for I have now been sent to you." While he was speaking this word to me, I stood trembling.
Dan 10:12 Then he said to me, "Do not fear, Daniel, for from the first day that you set your heart to understand, and to humble yourself before your God, your words were heard; and I have come because of your words.
The world judges according to appearance, we must judge righteously.
Joh 7:24 Do not judge according to appearance, but judge with righteous judgment."
Judging is not a contradictory statement. We must be righteous before we can judge correctly. If we have to make a judgment; we should look to the end of the matter, and make a judgment that will ultimately benefit the person being judged, even though the judgment may appear harsh in the short term. If we judge harshly, without all the facts; that is the way we will be judged. It is far better to judge ourselves against Christ, and change where we fall short. We should be able to make small judgments among ourselves: even suffering wrongfully, if we are converted.
