The world often takes this verse out of context and uses it to accuse Christians of being “judgmental” when they speak of sin. In the context of this verse Jesus is telling His disciples not to judge one another, something the Bible condemns (Rom. 14:10; James 4:11). In Luke 6:41,42 He speaks of seeing a speck in a brother’s eye. He also tells us that when we judge, we should use “righteous judgment” (John 7:24). If someone steals, lies, commits adultery, etc., the Christian can make a (righteous) moral judgment and say that the actions were morally wrong, and that these sins will have eternal consequences.
It is important to make it clear that whenever we speak about sin we are making a moral judgment, but it is based on God’s standards, not ours. The moral Law is the righteous standard by which all of us will be judged. So, helping people see how they will do when they stand before God on Judgment Day it is not being judgmental—it is being compassionate. Chuck Colson said, “True tolerance is not a total lack of judgment. It’s knowing what should be tolerated—and refusing to tolerate that which shouldn’t.”
Luke 6:37 “Judge not, and you shall not be judged. Condemn not, and you shall not be condemned. Forgive, and you will be forgiven.
