CS Lewis on God’s “Divine act of pure giving”

“If the world exists not chiefly that we may love God but that God may love us, yet that very fact, on a deeper level, is so for our sakes. If He who in Himself can lack nothing chooses to need us, it is because we need to be needed. Before and behind all the relations of God to man, as we now learn them from Christianity, yawns the abyss of a Divine act of pure giving–the election of man, from nonentity, to be the beloved of God, and there (in some sense) the needed and desired of God, who but for that act needs and desires nothing, since He eternally has, and is, all goodness.” (CS Lewis The Problem of Pain, chaps. 3, 44)
