for man's anger does not bring about the righteous life that God desires.God desires a righteous life for you. A life that is modeled by Christ Himself. God desires this, and according to Romans 8:28-29, God is working toward that end, in all things.
The phrase "bring about" has to do with working toward, or achieving. Your anger is not working toward that same end that God is working toward. Your anger is self-centered and self-motivated. Your anger is because of the failures of life to give you what you want. Whether it be a nice job or obedient kids or a spouse that respects you, if you don't get what you want, and it makes you angry... you are dealing with a heart idol, and that anger is working in the wrong direction. The anger is an energy boost, but if it is to still get what you want, it is not working about that righteous life that God wants for you.
Turn your hearts towards God's Kingdom. When you are angry, ask yourself why you are angry. Ask God to show you what His anger is all about.
