“My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, 20 because human anger does not produce the righteousness that God desires.” (James 1:19-20)
Many times other people do things to us that are wrong and sinful. But this does not mean that we have an excuse to lose our cool with them. First of all, we should give them a chance to explain themselves. Second of all, if they really have sinned against us, we must still love them, because God commands us to love even our enemies (Matthew 5:44).
