Anger is an intense emotional state involving a strong, uncomfortable and non-cooperative response to a perceived provocation, hurt, or threat. Proverbs 15:1 says a gentle answer makes anger disappear, but a rough answer makes it grow.
In Matthew 5: 21-24, Jesus teaches about anger
You must not murder anyone. Any person who commits murder will be judged.’ But I tell you, don’t be angry with anyone. If you are angry with others, you will be judged. And if you insult someone, you will be judged by the high court. And if you call someone a fool, you will be in danger of the fire of hell. “So, what if you are offering your gift at the altar and remember that someone has something against you? Leave your gift there and go make peace with that person. Then come and offer your gift.
Romans 12: 17-21, tells us
If someone does you wrong, don’t try to pay them back by hurting them. Try to do what everyone thinks is right. Do the best you can to live in peace with everyone. My friends don’t try to punish anyone who does wrong to you. Wait for God to punish them with his anger. It is written: “I am the one who punishes; I will pay people back, “says the Lord. But you should do this: If you have enemies who are hungry, give them something to eat. If you have enemies who are thirsty, give them something to drink. In doing this you will make them feel ashamed.” Proverbs 25:21 22 don’t let evil defeat you, but defeat evil by doing good.
Ephesians 4:26-32, explains
“When you are angry, don’t let that anger make you sin,” and don’t stay angry all day. Don’t give the devil a way to defeat you. Whoever has been stealing must stop it and start working. They must use their hands for doing something good. Then they will have something to share with those who are poor. When you talk, don’t say anything bad. But say the good things that people need whatever will help them grow stronger. Then what you say will be a blessing to those who hear you. And don’t make the Holy Spirit* sad. God gave you his Spirit as proof that you belong to him and that he will keep you safe until the day he makes you free. Never be bitter, angry, or mad. Never shout angrily or say things to hurt others. Never do anything evil. Be kind and loving to each other. Forgive each other the same as God forgave you through Christ.
My dear brothers and sisters always are more willing to listen than to speak. Keep control of your anger. Anger does not help you live the way God wants. So get rid of everything evil in your lives every kind of wrong you do. Be humble and accept God’s teaching that is planted in your hearts. This teaching can save you (James 1: 19-21).
