Anger is especially dangerous and damaging when the person who comes under its madness has any office of authority. He or she will wield that authority as a raging warrior wields his battle ax over the heads of any who displease him. Nothing is more destructive to the church than anger in a man of authority who uses that authority to bring hurt to to those he finds pleasure in hurting. This is another danger sign I should always be quick to cast off if it comes upon me, to find pleasure in hurting someone I have allowed myself to hate. Anger that is of God is for reasons of good and bad - it is never personal.
Carnal anger is always senseless and selfish.
Anger in the end destroys the person who tolerates it. Anger against a brother is the spirit of murder in the eyes of God. God's love is not present where hatred of a brother grips the soul. God's love in my heart is the only power greater than hatred. It is right to hate the evil deeds of a man or a brother - but never to hate the person of the sinner or the brother.
