What's the difference between judging others and constructive criticism?
Do not judge others, and you will not be judged. For you will be treated as you treat others. The standard you use in judging is the standard by which you will be judged. And why worry about a speck in your friend's eye when you have a log in your own? Matthew 7:1-3
Don't speak evil against each other, my dear brothers and sisters. If you criticize each other and condemn each other, then you are criticizing and condemning God's law. James 4:11
† One coach berates a player publicly for making a mistake in a game. Another coach waits until the game is over and tells the player privately how to avoid making the same mistake again. Though no one likes criticism----even when it is constructive-we sometimes need it. But it is much easier to receive criticism when it is offered gently and in love, rather than in a harsh or humiliating way. A judge criticizes with no effort to see the person succeed or improve. One who offers constructive criticism invests in building a relationship and helping the other person become who God created him or her to be.
You must make allowance for each other's faults and forgive the person who offends you. Remember, the Lord forgave you, so you must forgive others. Colossians 3:13
