Forgive your enemies, but never forget their names.
Let anyone among you who is without sin be the first to throw a stone.
You are goodness and mercy and compassion and understanding. You are peace and joy and light. You are forgiveness and patience, strength and courage, a helper in time of need, a comforter in time of sorrow, a healer in time of injury, a teacher in times of confusion. You are the deepest wisdom and the highest truth; the greatest peace and the grandest love. You are these things. And in moments of your life you have known yourself to be these things. Choose now to know yourself as these things always.
~ Neale Donald Walsch Quotes from Conversations with God
It is the act of forgiveness that opens up the only possible way to think creatively about the future at all.
