Throw it away!
The weapons to use against anger are praise and forgiveness. They work every time. Forgive the difficult ones. Throw the memory away. Then praise Me over and over. Poof! Anger is gone! It works every time. Ephesians 4:26-27 In your anger do not sin: Don’t let the sun go down while you are still angry, and do not give the devil a foothold. Ephesians 4:31-32 Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you. James 1:19-20 Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; for the anger of man does not produce the righteousness of God. Galatians 5:22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.
