A perfect man would never act from a sense of duty; heโd always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people) like a crutch which is a substitute for a leg. Most of us need the crutch at times; but of course it is idiotic to use the crutch when our own legs (our own loves, tastes, habits etc.) can do the journey on their own.
C. S. LewisNeed-love says of a woman "I cannot live without her"; Gift-love longs to give her happiness, comfort, protection - if possible, wealth; Appreciative love gazes and holds its breath and is silent, rejoices that such a wonder should exist even if not for him, will not be wholly dejected by losing her, would rather have it so than never to have seen her at all.
C. S. LewisWhen we want to be something other than the thing that God wants us to be, we must be wanting what, in fact, will not make us happy...whether we like it or not, God intends to give us what we need, not what we now think we want. Once more, we are embarrassed by the intolerable compliment, by too much love, not too little.
C. S. Lewis
