"The holiest of all the spots on earth is where an ancient hatred has become a present love." -- A Course in Miracles
We often say that we are "spiritual beings having a human experience". The "spiritual being" of us recognizes that each person is the beloved of God, that there are no victims, and every experience we have brings us a gift, a lesson and a blessing. Sometimes the "human experience" part of us doesn't get that far, and needs to forgive.
Forgiveness is truly the best gift we can give ourselves.
