'It may be infinitely less evil to murder a man than to refuse to forgive him. The former may be a moment of passion: the latter is the heart's choice. It is spiritual murder, the worst, to hate, to brood over the feeling that excludes, that, in our microcosm, kills the image, the idea of hatred.'
George Macdonald in Madeleine L'Engle, A Circle of Quiet, p.158.
