This is one of the things that love is called upon to do:
To affirm and sustain the seed in another human being even though no tangible evidence has been given of the nature and quality of the seed that is growing there. Love depends upon the capacity to reach beneath the surface of persons, to feel and touch the seed of life that is hidden there. And love becomes a power when it is capable of evoking that seed and drawing it forth from its hiding place.
To forgive means to give life, to remove what has been an obstacle to friendship and communion: those inner, psychological walls that had prevented dialogue or communicatíon. These walls are judgments that separate and isolate us from others and push people into anguish and inner death. To forgive means we no longer judge others. Forgiveness breaks down blockages to communication and communíon so that we can say to one another: I love you and want you to live.
