Corrie Ten Boom's example of forgiveness (from The Hiding Place) in which she describes an unexpected encounter with one of the Nazi guards who had mistreated her at Ravensbruck concentration camp, where her sister had Betsie died and she herself had been subjected to horrible indignities.
Corrie writes…
"It was at a church service in Munich that I saw him, the former S.S. man who had stood guard at the shower room door in the processing center at Ravensbruck. He was the first of our actual jailers that I had seen since that time. And suddenly it was all there - the roomful of mocking men, the heaps of clothing, Betsie's pain-blanched face.
He came up to me as the church was emptying, beaming and bowing.
"How grateful I am for your message, Fraulein," he said. "To think that, as you say, He has washed my sins away!"
His hand was thrust out to shake mine. And I, who had preached so often to the people in Bloemendaal the need to forgive, kept my hand at my side.
Even as the angry, vengeful thoughts boiled through me, I saw the sin of them. Jesus Christ had died for this man; was I going to ask for more? Lord Jesus, I prayed, forgive me and help me to forgive him.
I tried to smile, I struggled to raise my hand. I could not. I felt nothing, not the slightest spark of warmth or charity. And so again I breathed a silent prayer. Jesus, I cannot forgive him. Give me Your forgiveness.
As I took his hand the most incredible thing happened. From my shoulder along my arm and through my hand a current seemed to pass from me to him, while into my heart sprang a love for this stranger that almost overwhelmed me."
