SimchaMinute by Rabbi Avigdor Miller
Hashem put into a man certain middos of character like kavod or jealousy, kinah, or gaava...
Like an arm — You see somebody in the street with only one arm, we can imagine how difficult his life is. Yet when a person has two arms and he uses them to hit people, he’s misusing these wonderful gifts of Hashem.
Therefore all the middos must be utilized properly in order to fulfill their true function. — Gaining Glory by Giving Glory (#836)
