One is that they’re both very hard to express. How do you communicate to another person that a single sentence or facial expression can strike you at your core? How a joke about your appearance or a raised eyebrow that reminds you of an abuser can devastate you inside, even though you might retain your composure until you’re alone? Or, on the other side, that the smell of tea or the sound of Christmas music can instantly transport you to the happiest moment of your life? How can you get across to another person the sheer weight of what you’re feeling at the moment that that scar or that joy is tapped into?
The other is that they both, in their own ways, point to eternity. Because nothing purely worldly can honestly bind those deep wounds. And nothing flush with sin (as even the best of this world is) can replicate those deep joys, not even (as C.S. Lewis said) the moments themselves, should we be able to re-live them; after all, it was the longing for some permanence like the grandmother’s embrace or the Christmas morning that made our hearts sing. It was the longing, not the smell or the sensation or the sound itself. These wounds and joys are signposts.
The pains of my innermost heart, the insecurities I can’t even express and fears that strike me like a hot iron in the middle of the night, can’t be fully resolved by anything but the triune God. And the happinesses I most want to taste, the ones merely echoed in the cleanest, brightest moments of my childhood or most momentous occasions of my adulthood, aren’t going to be completely realized on this side of the eschaton. Pain won’t be fully left behind and joy won’t be fully consummated until the Lamb of Israel and Lion of Judah returns.
Incommunicability and pointing to eternity: Two qualities our deepest pains and joys share.
Two notes they both sing well, though on different sides of the shadow.
