When you forgive someone, you slice away the wrong from the person who did it. You disengage that person from his hurtful act. You recreate him. At one moment you identify him ineradicably as the person who did you wrong. The next moment you change that identity. He is remade in your memory.
You think of him not as the person who hurt you, but a person who needs you. You feel him now not as the person who alienated, but as the person who belongs to you. Once you branded him as a person powerful in evil, but now you see him as a person weak in needs. You recreated your past by recreating the person whose wrong made your past painful.
-Lewis Smedes (on a book entitled What’s So Amazing About Grace by Philip Yancey)
