Cara Mia, if that man has not separated you from the love of God, and he has not, then the only thing keeping hate of him alive is your thought about him. Only your pride keeps him in your memory. Dissolve your pride, and you dissolve your hate. To be still possessed of the hate that pain made is not intelligent. Take care. It can sap your energy to what you know to be your purpose. By being troubled about it, you have already discovered it to be unworthy of your grander aims, and that is the beginning of humility.
We are all wanderers in the earth, but only a few of us in each generation have discovered the life of charity, the living from day to day, receiving gifts gratefully through grace, and rendering them, multiplied through grace, to the Giver...the grateful rendering, the gratitude and giving.
