In The Four Loves, C.S. Lewis wrote, "There is no safe investment. To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly be broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements; lock it up safe in the casket or coffin of your selfishness. But in that casket - safe, dark, motionless, airless - it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell. I believe that the most lawless and inordinate loves are less contrary to God’s will than a self-invited and self-protective lovelessness. ...We shall draw nearer to God, not by trying to avoid the sufferings inherent in all loves, but by accepting them and offering them to Him; throwing away all defensive armour. If our hearts need to be broken, and if He chooses this as a way in which they should break, so be it. What I know about love and believe about love and giving ones heart began in this."
I think this statement raises relevant questions of various sorts for all of us. There is likely nuance and context to this which I am overlooking, but it nonetheless provokes many thoughts for me, especially around the need for vulnerability. It doesn't come naturally to me. And an experiment or two in vulnerability were badly chosen and therefore ended poorly, but I think it's important enough to bite the bullet and try it more. There's truly liveliness to be found in real love.
