Hope is a state of mind, not of the world. Either we have hope within or we don't; it is a dimension of the soul not essentially dependent on some particular observation of the world or estimate of the situation. It is an orientation of the spirit, an orientation of the heart; it transcends the world that is immediately experienced and is anchored somewhere beyond its horizons.
What keeps us from forgiving the people who hurt us is that we have not yet healed the wounds they inflicted. Forgiveness is the gift at the end of the healing process. We find it waiting for us when we reach a point where we stop expecting "them" to pay for what they did or make it up to us in some way. Yet, forgiveness is moving on. It is recognizing that we have better things to do with our life and then doing them.
