“He lay awake most of that night. It came over him that now he understood one thing: a conflict had been waged in the whole of Creation since the dawn of the ages between God and His enemy, and all that had life, soul or spirit took part in the fight in one host or the other, whether they knew it or not–angels and sprites, men here on earth and on the farther side of death. And it was most commonly by a man's own cowardice that the Devil could entice him into his service–because the man was afraid God might demand too much of him–command him to utter a truth which was hard to force through his lips, or to abandon a cherished delight without which he believed himself not strong enough to live: gain or welfare, wantonness or the respect of others. Then came the old father of lies and caught that man's soul with his old master-lie–that he demanded less of his servants and rewarded them better–so long as it lasted. But now Olav himself had to choose whether he would serve in one army or in the other.”
