C. S. Lewis on the Overflowing Goodness of God

Quote from The Screwtape Letters, Uncle Screwtape, a senior demon, describes to his ghoulish nephew how the true God - Father, Son and Spirit is utterly different from his master - the Devil:

One must face the fact that all talk of his [God's] 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 - creatures, whose life, on it's miniature scale, will be qualitatively like his own, not because he has absorbed them, but because their wills freely conform to his. We want cattle who 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.
