Almighty, all-merciful God, through Christ Jesus you have taught us to love one another, to love our neighbors as ourselves, and even to love our enemies. In times of violence and fear, let the peace of Christ rule in our hearts, so that we may not be overcome with evil but overcome evil with good. Help us to see each person in light of the love and grace you have shown us in Christ. Put away the nightmares of terror and awaken us to the dawning of your new creation. Establish among us a future where peace reigns, justice is done with mercy, and all are reconciled. We ask these things in the name and for the sake of Jesus Christ our Lord. Amen.
