“Pursue peace with all people, and holiness, without which no one will see the Lord: looking carefully lest anyone fall short of the grace of God; lest any root of bitterness springing up cause trouble, and by this many become defiled.”
Sudden anger is to be controlled until you have a chance to think it through. Sinful anger is to be condemned immediately. Stubborn anger is to be conquered. How are you going to conquer it? You’ve got to trace it back and say, “Why am I such an angry person?” You’ve got to go back to find out where that root of bitterness is because, no matter how much you pick the tops off those dandelions, the roots are there; you need to get to the root of the matter and analyze it.
Ephesians 4:31 says, “Let all bitterness, wrath, anger … and evil speaking be put away from you.” If you’re not willing to put it away, God’s not going to do it for you. The Greek word for repentance, metanoia, means “a change of mind.” Until you choose against bitterness, wrath, anger, and evil, nobody is going to choose against it for you.
Make a list of areas in your life where you’re particularly prone to anger. Ask God to help you trace the roots of this anger and repent as needed.
