First he says that our knowledge of our reality is fragmentary – a dim reflection in a mirror, a riddle, an enigma; and that “when perfection comes,” that is, truth as he has defined above, then and only then can we see “in reality and face to face!” He further amplifies this by saying, “Now I know in part; but then I shall know and understand fully and clearly … as I have been fully and clearly known and understood by God.”
So we can see that what Paul is striving to convey to us is that love and truth are the same things, intertwined, inseparable. And this is the definition of knowledge as the Cassiopaeans have explained it: “To love you must know. And to know is to have light [i.e. truth]. And to have light is to love. And to have knowledge is to love.” I was a hidden treasure and I loved to be known, so I created man in order that I may be known.
