I read recently that forgiveness is a death, and the biggest forgiveness of all is Jesus's death on the cross.
And I just want to say that before a person can forgive, that person has to grieve the loss of whatever it is-- a relationship, a dream, a position, a place. Maybe that is what the Man of Sorrows did here on earth with all his loving of us and healing of us and chastising of us, and with his praying in the Garden of Gethsemane when his friends couldn't even stay awake with him in his grief. They never understood his mission until after his resurrection, and they chastised people who did understand, for being wasteful and bothering the Master. The people closest to him for the most part were just like Job's miserable comforters.
And I just want to say that grieving is a process and forgiveness is a process, and the greatest example of that process is Christ on the cross. He loved them, he shook his head, he kept dropping hints for those who had ears to hear, and, finally, he spread forth his hands, and he died. He also arose, and God will give us beauty for ashes if we wait long enough. He gave Job more than he had in the beginning, he gave Jesus ALL his people, and he will give us blessings, too.
Wherever you are in the process, be comforted-- blessings in good measure, pressed down, and shaken together, will he give us.
