Alan Jacobs:

In my judgment, it is the opportunity to receive and extend forgiveness that is the greatest possible inducement to repentance and amendment of life, and — I cannot stress this too strongly — a shared repentance and amendment of life make genuine community possible…. We will join the prophets and cry out for justice to roll down like waters, and righteousness like an ever-flowing stream. But we will also echo St. Paul and tell you that we Christians forgive others because God in Christ has forgiven us. We will tell you that your shortcomings and failures can never outpace the mercy of God, who loves his wayward children, all of them, and will someday wipe from their eyes every tear. This is the great hope of those who wound as well as those who are wounded. And all of us sometimes wound and sometimes are wounded.

Yes, “no justice, no peace.” But also “no mercy (and repentance and ammendment of life), no peaceful community.”
