To stop anger or rage you have to address unresolved guilt, shame, fear, and hate from your past. To overcome these type of hurts, you need prayer, courage, determination and faith.
I wish I could tell you I have mastered this, but I haven't. I can tell you I have acknowledged my guilt, my shame, my fear, and my hate from my past. Yes, and my pain too! I am fully aware of my triggers and what sets me off. This gives me a tremendous edge when the anger demon appears. I pray unceasingly to become the best version of myself daily and I know love always wins!

To The Gift Giver
It seems so simple, Lord. You don't ask anything complicated. Why do we stray so often? Because there is a battle going on and the enemy uses weapons of mass distraction!  Give us the sight and the knowledge to see such for what they are. Calm our agitated souls so that we might stay with what is real and walk with what is best of all. You, Lord!

He has shewd you, O man, what is good; and what does the Lord require of you, but to do justly, and to love mercy, and to walk humbly with your God. - Micah 6:8
