21 “You have heard that it was said to those of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’ 22 But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, ‘Raca!’ shall be in danger of the council. But whoever says, ‘You fool!’ shall be in danger of hell fire (Matthew 5:21–22, NKJV).”
Jesus challenges us to inspect our attitudes toward others and the words they prompt us to use (Matt. 12:33-37). Brotherly kindness and love (attributes Christians add to our faith, 2 Peter 1:5, 7) go far beyond not murdering a person. The apostle John assures us that “whosoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him” (1 John 3:15). Jesus expects citizens of the kingdom to follow a path that leads from hate to harmony. Unjustified anger, contemptuous words, and hateful conduct bring a judgment that endangers the soul. So, we must be careful how we speak to others and speak of them to others. We must remove animosity, contempt, bitterness, malicious speech from our hearts and mouths (Eph. 4:31). Kindness must prevail to be a faithful follower of Jesus (Eph. 4:32). Remember, “A wholesome tongue is a tree of life, but perverseness in it breaks the spirit” (Prov. 15:4). Furthermore, the perverse tongue condemns the soul.
