Lewis' Screwtape

This book, in case you haven't read it, is a hypothetical conversation between two demons, Screwtape and his nephew Wormwood. It is a conversation about the temptation and projected demise of a fictional man. This excerpt is Screwtape talking to his nephew about what humans are in their eyes.

"To us a human is primarily food; our aim is the absorption of its will into ours, the increase of our own area of selfhood at its expense. But the obedience which the Enemy demands [ the Enemy=God in this context] of men is quite a different thing. One must face the fact that all the talk about His love for men, and His service being perfect freedom, is not, (as one would gladly believe) mere propaganda, but an appalling truth. He really does want to fill the universe with a lot of loathsome little replicas of Himself..We want cattle who can finally become food; He wants servants who can finally become sons. We want to suck in, He wants to give out. We are empty and would be filled; He is full and flows over.?
