Forgiveness means accepting the core of every human being as the same as yourself and giving them the gift of not judging them. You can be clear about whether or not a person's behavior is acceptable without judging the person. Forgiveness starts with ourselves and extends to others. Accepting that the core of your own being is as precious and wonderful as that of any other person is the greatest gift you can ever give yourself.
If we have been called to unity, the way to God, for us, passes through our neighbor. It is through this passage, which may sometimes be as dim and dark as a tunnel, that one comes to the light. This is the mysterious path God invites us to take. Each day there are opportunities to perfect this art, a tiring one at times and exhausting, but always wonderful too, vital and fertile, the art of "making ourselves one" with other people: the art of loving.
