So, as I said in an earlier post, I've been reading Piers Anthony's "Incarnations of Immortality" series. Basically in each of the books, you are following the experiences of one of the Incarnations (Death, Time, Fate, War, Nature). The Incarnations are mortals, who (for a time) become immortal to fill the office. There are also two "Immortals" (God and Satan) who are actually Incarnations themselves (Good and Evil respectively), just longer lived. So the Incarnations are basically trying to foil Satan from meddling in the affairs of mankind (God and Satan covenanted at the beginning to not interfere, and just let mankind muddle along. God, being good, honors His covenant, while Satan, being evil, cheats outrageously).
Each Incarnation has to face Satan in their own terms, thwarting him with the powers unique to their own office.
So I just finished "Weilding a Red Sword" (War), and at the end there was a line that struck me as profoundly true. Even though Mr. Anthony professes not to believe in the supernatural of any kind (which explain his version of God, who does not involve himself in human affairs), I think he hit the nail on the head. (I love finding little truths in the fiction I come across. I've done it with Star Wars, Star Trek, Harry Potter, Lord of the Rings...)
If I may quote:
" This matter is larger than any single person or any single episode. Satan is an insidious corruptor who never rests and he is most dangerous in seeming defeat, as all of us know. It is his specialty to proffer a large reward for a very small compromise, for his resources are infinite. But he who accepts the first compromise has made a precedent, and it then becomes easier to accept the next, and the next, until at last Satan has after all won. Only by refusing any compromise at all, no matter how grotesquely uneven the stakes seem to be, can a person be proof against the insidious devices of the Master of Evil."
