I wouldn't call that serving, you see. I call that sort of relationship friendship, myself. A respectful friendship, of course, but a friendship. I suppose there are elements of service involved, but I don't see it as serving, though semantically I suppose you're correct. A lot of christians, I suppose, would say they have a similiar relationship with God/Jesus/the trinity etc. (though they call magick 'prayers', as to admit the existence of a supernatural power available to anyone would de-validate the existence of miracles, anyhoo...) but I can never help myself but see servitude under wrathful old Jahweh as being anything but, well, tyrannical. The god of the bible is a paranoid spiritual construct, an uber-patriarchal totem created by weak men who demands endless praise from his followers during and after life, and hands down edicts restricting pretty much every area of their earthly existence. The reason I don't like a lot of, especially conservative, christians is that they ignore these rules until they get to one they like (like 'no gays').
Clearer? Sorry, I'm allergic to paragraphs.
