Yes, as a child of God you have to judge if the Holy Spirit leads you, else you will never be able to uphold the requirements of the Lord against sin in self and the community.
When you see somebody doing wrong, do you bury your head or walk off, when you know by the Holy Spirit’s prompting that you should go ahead to help the poor brother or sister stop injuring themselves so that he or she does not persist in wrong-doing leading to bankruptcy or even suicide?
The prophets in the Old Testament were judges. Many Christians hide behind the words of Matthew 7:1-6 and accept and erroneously live lives below the standards of the Word of God because they believe they cannot judge.
1. Judge not, that ye be not judged.
2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. Mk. 4.24
3 And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye?
4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?
5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.
6 ¶ Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
I was thinking about this passage, for as Christians we have to judge whether some activity is according to the Word of God or not. This main thought here is do not be a hypocrite. Do not judge if you do not live it. However, the Word of God behoves us to be more and more like Jesus. The caveat for judging others is, we must not be hypocrites – that means we must not be caught contravening the Word of
God and then condemning others for contravening it. For example the woman who was caught in adultery – those who lived in adultery would be hypocrites if they judged her and not themselves first.
Matthew Henry’s Concise Commentary
We must judge ourselves, and judge of our own acts, but not make our word a law to everybody. We must not judge rashly, nor pass judgment upon our brother without any ground. We must not make the worst of people. Here is a just reproof to those who quarrel with their brethren for small faults, while they allow themselves in greater ones. Some sins are as motes, while others are as beams; some as a gnat, others as a camel. Not that there is any sin little; if it be a mote, or splinter, it is in the eye; if a gnat, it is in the throat; both are painful and dangerous, and we cannot be easy or well till they are got out. That which charity teaches us to call but a splinter in our brother’s eye, true repentance and godly sorrow will teach us to call a beam in our own. It is as strange that a man can be in a sinful, miserable condition, and not be aware of it, as that a man should have a beam in his eye, and not consider it; but the god of this world blinds their minds. Here is a good rule for reprovers; first reform thyself.
This is the very most difficult aspect in the community of saints. Should we allow sins defined by the word of God to continue when we know it is against God’s word? There is no question there should be discernment and in the resolution of judgement, there should be propriety. However, there is a line beyond which a spade should be called a spade and this is where most would not want to be the the bearer of bad news to the one being judged lest the same judgement becomes a boomerang.
Should a Christian judge? Yes in humility and only consistent with the Word of God, if he himself is not guilty of the sin being judged against another.
This is not to say the man of God is perfect or any of the leaders are perfect. The person who is judging should not be caught in the same sin lest he be proved a hypocrite. That is when we MUST not judge.
We must judge ourselves first and then only are we qualified to judge others. May the Lord help us to improve ourselves with His help and help others become better even if it involves judging them as led by the Holy Spirit.
