What does the Bible say about judging others?
In a nutshell, yes, we can critic or make a moral judgment of someone. However, make sure you also have the best interest of the other person. Otherwise, you could just be judging, which makes it a sin.
Matthew 7:1 is the most frequently quoted Bible verse today: “Do not judge so that you won’t be judged.” Theologist Paul Copan said, “It’s been twisted to mean we can’t say someone’s action or lifestyle is wrong.“
However, when someone says, “Don’t judge,” he’s judging you for judging someone else. You’ve done wrong by saying someone else has done wrong.
Jesus made moral judgment too
Jesus too made a moral judgment by using metaphors like “dogs and pigs” to people undeserving of grace. Such descriptors were debasing in Jewish culture (Mt. 7:6).
Yet He told us not to judge based on appearance (John 7:24). The thing is, Jesus alone knows the hearts of men. He is our judge.
How do we resolve the apparent tension?
In Matthew 7:5, Jesus said to first examine ourselves (removing the log from our own eye), before helping (or criticizing) others.
Therefore, if you are sure that the Holy Spirit is telling you to “rebuke” someone, the right kind of judging is doing it with a humble attitude, keeping in mind that like others, you too are a sinner.
