C. S. Lewis Quote

The mold in which a key is made would be a strange thing, if you had never seen a key: and the key itself a strange thing if you had never seen a lock. Your soul has a curious shape because it is a hollow made to fit a particular swelling in the infinite contours of the divine substance, or a key to unlock one of the doors in the house with many mansions.

The Problem of Pain (1940)
