One of the most misunderstood and misapplied scriptures in the Bible is Matthew 7:1. In this verse Jesus said, “Judge not, that you be not judged.” It’s a verse that many believers toss around with little or no understanding. As Christians, we are most certainly called to judge. Our judgement is based on the only standard in the world that will never change: the Word of God. Beyond that, there is an overriding characteristic that ought define the Christian’s disposition at all times. Charity. Charity should set us apart in all of our judgements. Listen to how J.C. Ryle explains the meaning of this little verse:
“Our Lord does not mean that it is wrong, under any circumstances, to pass an unfavorable judgment on the conduct and opinions of others. We ought to have decided opinions of others. We are to “prove all things.” We are to “try the spirits.” – Nor yet does He mean that it is wrong to reprove the sins and faults of others, until we perfect ourselves. Such an interpretation would contradict other parts of Scriptures. it would make it impossible to condemn error and false doctrine. It would debar any one from attempting the office of a minister or a judge. The earth would be “given into the hands of the wicked.” (John ix.24) Heresy would flourish, wrong doing would abound.”
“What our Lord means to condemn is a censorious and fault-finding spirit. A readiness to blame others for trifling offences, or matters of indifference–a habit of passing rash and hasty judgments–a disposition to magnify the errors and infirmities of our neighbors, and make the worst of them–this is what our Lord forbids. It was common among the Pharisees. It has always been common from their day down to the present time. We must all watch against it. We should “believe all things,” and “hope all things “about others, and be very slow to find fault. This is Christian charity. (1 Cor. 13:7.)”
