The Bible does not say anger is always sin — Jesus grew angry at injustice. It says: "Be angry, and don't sin. Don't let the sun go down on your wrath" (Ephesians 4:26). Anger is a fire: useful in the fireplace, devastating on the carpet.
Biblical wisdom attacks anger at both ends: slowing the entrance ("slow to anger," James 1:19) and speeding the exit (never letting it spend the night). In between, the gentle answer that "turns away wrath" (Proverbs 15:1).

Frequently asked questions about anger

How do I manage my anger biblically?

What about anger at God?
The psalms are full of believers shouting their incomprehension at God — and he does not strike them down, he listens. Anger laid before God is better than bitterness hidden away from him.
