Holding on to anger, resentment and hurt only gives you tense muscles, a headache and a sore jaw from clenching your teeth. Forgiveness gives you back the laughter and the lightness in your life.
In the evening of life we shall be judged on love, and not one of us is going to come off very well, and were it not for my absolute faith in the loving forgiveness of my Lord I could not call on him to come.
All major religious traditions carry basically the same message, that is love, compassion and forgiveness the important thing is they should be part of our daily lives.
You've just got to have a sense of respect for the person you have children with. Anger doesn't help anybody. Ultimately you have to say forgiveness is important, and honoring what you had together is important. But it's easy to say and harder to do.
For me, forgiveness and compassion are always linked: how do we hold people accountable for wrongdoing and yet at the same time remain in touch with their humanity enough to believe in their capacity to be transformed?
