Corrie Ten Boom survived the horrors of a WWII concentration camp. Years later she spoke widely of her experience of the power of forgiveness teaching, "Forgiveness is not an emotion. Forgiveness is an act of the will." After one such speaking event, one of her former camp guards recognized her, approached her, and stuck out his hand to shake hers. She recounted, "I, who had preached so often … the need to forgive, kept my hand at my side. And so … 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. And so I discovered that it is not on our forgiveness any more than on our goodness that the world’s healing hinges, but on His."
