Bitterness rents a room in the soul to the one we hate. "To forgive is to set a prisoner free and discover that the prisoner was you."
Forgiving is not forgetting the crime, excusing it, or pretending that its pain is not horrific. Forgiving is pardoning—choosing not to punish. It is giving up your right to hurt the one who hurt you. It is something we do for the sake of the one who hurt us, and even more for ourselves.
Is there unpardoned pain in your heart this morning? You can ask God to forgive the one who hurt you, and ask him to help you do the same. And you will learn that "forgiveness is the giving, and so the receiving, of life."
