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.
Ahead, but looking back the very light
That blinded us shows us the way we came,
Along which blessings now appear, risen
As if from sightlessness to sight, and we,
By blessing brightly lit, keep going toward
That blessed light that yet to us is dark.
