He best keeps from anger who remembers that God is always looking upon him.
While I understand the passions and the anger that arise over the death of Michael Brown, giving into that anger by looting or carrying guns, and even attacking the police, only serves to raise tensions and stir chaos.
The more anger towards the past you carry in your heart, the less capable you are of loving in the present.
In general I was a good kid. It usually took a lot to make me mad. But once I reached the boiling point, I lost all rational control. Totally without thinking, when my anger was aroused, I grabbed the nearest brick, rock, or stick to bash someone. It was as if I had no conscious will in the matter.
Whatever is begun in anger ends in shame.
