You are told to love your neighbor as yourself. How do you love yourself? When I look into my own mind, I find that I do not love myself by thinking myself a dear old chap or having affectionate feelings. I do not think that I love myself because I am particularly good, but just because I am myself and quite apart from my character. I might detest something which I have done. Nevertheless, I do not cease to love myself. In other words, that definite distinction that Christians make between hating sin and loving the sinner is one that you have been making in your own case since you were born. You dislike what you have done, but you don't cease to love yourself. You may even think that you ought to be hanged. You may even think that you ought to go to the police and own up and be hanged. Love is not an affectionate feeling, but a steady wish for the loved person's ultimate good as far as it can be obtained.
--C. S. Lewis from God in the Dock
