"People with understanding control their anger; a hot temper shows great foolishness." (Prov. 14:29)
"A gentle answer deflects anger, but harsh words make tempers flare." (Prov. 15:1)
"Stop being angry! Turn from your rage! Do not lose your temper -- it only leads to harm." (Psalm 37:8)
Sometimes people talk about being in a bad mood or say they woke up on the wrong side of the bed. This may be true, but Christians are told that feelings should not prevent them from controlling certain behaviors. Feelings come and go so it is unwise to let feelings control emotions, thoughts and actions, especially if the feelings are negative and bring about cruel words or harmful actions. Scripture teaches that through the power of God, we can learn to overcome anger and control our emotions.
"Don't sin by letting anger control you. Don't let the sun go down while you are still angry." (Eph. 4:26)
This Scriptures confirms that anger is a sin if it controls a person. It also implies that it is possible to control anger, which is through prayer and calling on the Holy Spirit. When troubling situations arise, take time to think about whatever or whoever is causing the problem, and look to God for the way through. Don't freak out or explode because once that happens, anger is even harder to control.
The second half of Ephesians 4:26 asks Christians to work things out quickly and to not go to bed angry. Words spoken cannot be taken back, and some actions can be so fueled by anger that they lead to physical injury, a trip to the hospital, police action and even prison. That's how damaging anger is. Every day in the newspapers, on TV or Internet, there are stories of crimes committed because of rage. It is better to decide to be someone who is not controlled by their feelings.
"Get rid of all bitterness, rage, anger, harsh words, and slander, as well as all types of evil behavior." (Eph. 4:31)
"But now is the time to get rid of anger, rage, malicious behavior, slander, and dirty language. (Col. 3:8)
