Don't abandon Jesus. Truth and power are still to be found in the real Jesus. Anger hides and sneaks into your personality and into your life with great destructive force. Anger turns you against yourself and depletes your energy and health. Religion that creates hostility between people and that intentionally sets people against other people is alien to God, the universe and objective rational thinking.
Anger is contagious.
Angry preaching produces angry people. Judgmental preaching produces hypocrites. Conquer your anger, or your anger will conquer you.
