Accept the reality of the things that have happened, but do not let them cloud and poison your heart. If you are to be a positive influence on the world, you need to forgive.
“The problem with revenge is that it never evens the score. It ties both the injured and the injurer to an escalator of pain. Both are stuck on the escalator as long as parity is demanded, and the escalator never stops.” – Lewis B. Smedes
“To forgive is to set a prisoner free and discover that the prisoner was you.” – Lewis B. Smedes
The person you hold a grudge against isn’t necessarily hurt by this – they go on living their life whilst you are the one stuck dwelling on the things you feel they did. You are the one that continues to hurt inside, while the other person is out dancing.
