Where love is strong, forgiveness can be there for us before there is any movement on our part. Something special happens when forgiveness is given fulfillment by its recognition and acceptance. Sorrow and understanding can be involved in healing. The words needed may be, "I’m sorry," and it may take time before it is clear that the words are real. But forgiveness is given, not earned. Healing may take time; the forgiveness is gift. Where there is love, the gift will not be withheld.
Peace always begins within each of us. Our ability to create in the world depends on our ability, first, to work to create peace in our own lives. It's much easier to advocate peace on Earth than it is to be able to bring peace your own home. Or your own heart.
