Peace is a rejoicing. It is God's victory , over violence of every kind. Peace means praying for our enemies. It means forgiveness, on the cross. It means refusing to honor, or to take part in, the divisions and walls which people have set up between each other.
Peace means obedience, and love, and trust, and transformation.
It means building a new world, beginning in our very midst. Part of what peace means, is creating a community, where we don't just wait around and sit on our hands and pray for peace. We live it. That's in the present tense. Part of what we need to do as Christians, is to feel and know the peace that God gives, and then live from that place of peace, to let it grow, naturally, into every area of our lives.
