Anger is a normal emotion; we will possess anger, but how we react is the important part. That is what sets the emotional aspect of anger and anger that is unpleasing to God apart. In times of tension, we must be sensitive and measure our every word and action. Mindless reactions without first reflecting will only lead to continuous anger, but patients will pave a way for understanding and learning each other's differences.
(Proverbs 14:29) "Slowness to anger makes for deep understanding; a quick-tempered person stockpiles foolishness."
