Mythos in relationships and the inconsolable longing after God

Anyone who read my post muddling through Tim Keller's book The Meaning of Marriage on Singleness and searching for your "mythos", must, must now read this post by Lucidus, in which she has done the hard work of disentangling CS Lewis's "inconsolable longing", or Sehnsucht, from the realm of romantic relationships. After writing that post the other day and thinking a little more about Sehnsucht as I had previously understood it, as a piercing desire/longing for something not in this world that points us to God, I have kept shaking my head in some confusion about the appropriate place for this horizontal element of "mythos". Lucidus has articulated why, and it is well worth a read.
