What is human anger? It’s anger that occurs when someone rubs against our pride or selfishness. God still wants us to get angry, but for the right reasons such as the injustice of orphans or widows. Learn to temper your selfish anger. When you feel yourself getting angry because your feelings are hurt, swallow it and focus your mind on something else. Stewing in your anger only produces more anger. Practice refocusing your mind as many times as needed.
Human anger does not produce the righteousness God desires.
~ James 1:20 [NLT]
