“What causes quarrels and what causes fights among you? Is it not this, that your passions are at war within you?” James 4:1. ESV.
Your anger isn’t because of people and things around you. It’s because of the selfish desires that war in your heart.
Most likely your anger isn’t because of wanting to bring glory to God, it’s probably because you’re not getting what you want.
You don’t need anger management you need worship adjustment. You need idol awareness. Who rules your heart? Christ or self?
With Christ ruling my heart I’m able to be humble, kind, patient, forgiving, merciful, and loving. I can love because He first loved me!
