Whether married or celibate, people who live in the same bower for ten or twenty years may rarely if ever come to shouts and blows, but they often develop great skills in enmity. We know exactly how to wound each other and do it with economy and almost surgical precision, often with a simple shrug, the movement of an eyebrow, or just silence. We could give the CIA lessons in covert activities and sabotage. We might even keep our hand on it for good luck. We all have such buttons, of course, which is why we build strong defenses around our precious little world while trying to undermine that of the boor next to us.
Good walls make good neighbors.
Fullness, perfection, lies in anticipating the needs, hopes, wants, and desires of our neighbor. And being ready at all times to forgive. Jesus says we are to be like that. He commands us to be compassionate and merciful the way God is compassionate and merciful. That's a tall order.
