“[…] Evil appears quite different when seen from the point of view of eternity than when seen from within the kingdom of time. Up yonder one sees that it actually always serves Good in the long run. It is, so to speak, a contradiction in itself. It is constantly striving for power over Good, but without Good it could not exist – and if it ever achieved total power, it would have to destroy precisely that over which it desires to wield said power. That’s why it can last only as long as it is incomplete […]. If it were complete, it would cancel itself out. That’s why it has no place in eternity. Only Good is eternal, for it contains itself without contradiction.”
