I imagine the heart as a piece of fine quality marble; a pale stone with fine light gray threads running through it.
I imagine that life is a chisel at times. When we hear sad information about people we care about, the chisel chips our heart and leaves a space from the missing piece. When someone we love says hurtful words to us or takes actions against us that hurt, the chisel of life chips at the heart again and leaves another space from a missing piece.
I imagine that life is spackling paste at times. When we hear about something wonderful happening to people we care about, the paste is applied to the missing spot in our marble heart. When someone we love says things to us that make us happy and safe, another application of spackle is applied to a chipped place in our heart.
Our goal, hope and efforts in life are to end up having a heart that is whole – even if the patches show – rather than have chipped pieces missing.
