One thing that I appreciate about a stone is its hardness. A stone may be small like a mustard seed but once it gets into your eye, expect some infections. It can be so big, as well; big enough to take refuge from it and big enough to use it as a weapon against your foes.
Now, no matter how big or small a stone is, this small heart of mine desires to acquire such hardness. Hardness that makes it numb for things that don’t really matter anymore. Hardness that covers a soft spot against abuse and malpractice of emotions; and hardness that can only be softened by love… and nothing but pure love.
For no one can fully understand a man’s heart not even its steward. But fear not for God assures us that though the heart is hopelessly dark and deceitful, like a puzzle that no one can figure out, it is God who searches the heart and examines the mind. He gets to the heart of the human. He gets to the root of things. He treats them as they really are, not as they pretend to be. (Jeremiah 17:9-10)
