Joseph's Example of Forgiveness

Theolog Alexander Zikic pointed out in theological school chapel today that when someone does something evil to us we can feel that, in order to forgive that person, we need to decide, as if we were God, that what the person did actually wasn't evil. But Joseph provides a good example of how we should actually approach forgiveness; he said,

Do not be afraid, for am I in the place of God? But as for you, you meant evil against me; but God meant it for good, in order to bring it about as it is this day, to save many people alive. (Gen 50:18-20)
