What does God say about how we should handle anger?
Proverbs 29:11,20
(11)A fool vents all his feelings, but a wise man holds them back. (20) Do you see a man hasty in his words? There is more hope for a fool than for him.
The problem with anger is that it may lead us to lose control of our conduct and lash out at others with foolish words or deeds that are intended to hurt others and may be regretted later. By contrast, a wise man will control himself, even when he is angry.
The Bible teaches that our words and deeds are controlled by our thoughts. We must learn to control our thoughts and emotions, because harboring sinful thoughts will lead to sinful conduct. [Prov. 4:23; Matt. 15:18]
Ephesians 4:31,32
Not all anger is sinful (v26), but we should put away anger that is associated with bitterness, clamor (“loud quarreling” – NKJV), evil speaking, and malice. It is the opposite of kindness, tenderheartedness, and forgiveness (v32).
Anger is sinful when it leads us to lose control so that, instead of being helpful to others, we become abusive, saying evil or hateful things intended to hurt them. Or we may simply not care about how we affect them. [Col. 3:8; 2 Cor. 12:20]
