But now in Christ Jesus you who once were far away have been brought near by the blood of Christ. For he himself is our peace, who has made the two groups (Gentile and Jew) one and has destroyed the barrier, the dividing wall of hostility. His purpose was to create in himself one new humanity and in one body reconcile them both to himself through the cross, by which he put to death their hostility. - Ephesians 2:14-16
You removed all hostility that exists between your Father and people and any hostility that exists between sinners who hurt one another. In that single, solitary act of dying for both perpetrator and victim, you reconciled everyone in all directions in one instant. Help me take what you did for us on the cross and make it the reason and the power that I declare myself reconciled to the people who have hurt me or let me down. Use your gospel to remove the hostility between people I don’t like and me for my own "good" reasons. Give me peace that makes me boldly live in the presence of folks that give me the willies. Give me the cross shaped love that keeps me from being unhappy to see anyone. Use your salvation to save me from my own unhealthy aloneness.
In heaven you will have the joy of not being angry with anyone. Why not get a head start and stop being angry now.
