Is the Danger of Loving Worth the Danger of Not?

"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..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." - C.S. Lewis

"Lock it up safe in the coffin of your selfishness." 

If you know me or my blog at all this will not be the first time you've heard this thought, but never stated so penetratingly like this. (Thank you, Lewis) Is the danger of loving worth the danger of not? 

Let me just close with another quote:

"What we obtain too cheap, we esteem too lightly.... Heaven knows how to put a proper price upon it's goods." -Thomas Paine
