I'm not sure if this is theology or philosophy or psychology . . . Could lead to a theology of human beings I suppose (what do we call the 'theology of man' nowadays?) Anyway, some Sunday laziness . . .
People are like marshmallows with a nail in the middle - the nail completely covered by marshmallow. When we meet them we meet the marshmallow part. Some people are great fat marshmallows - friendly, cheerful, ever-loving people, some are dry and brittle - they don't have much in the way of social skills, although they may try. And others are everything in between - thin layers of marshmallow, thick, patchy and so on.
As we get to know people we start to work through the marshmallow, until eventually we encounter the iron core. Here we find the values held by the person. The things that make them strong and give them meaning in this world. The part where the Bible says, 'as iron sharpens iron, so one man sharpens another' (or something to that effect!). When iron meets iron real friendship are formed. Friction also happens. But we are beyond the world of marshmallow. We are pleased to share our iron with each other. Unfortunately, at the core with the iron are crumbs of clay. As people find our strength, they also find our weakness and insecurity. We'd rather not let those be seen - or see those of others. But it's part of the package. Also in the core we may find a pool of tears. It may be bigger or smaller, but it is there forming part of the human being. It may be well-hidden, but, be sure, it is there.
Our challenge in life is to love people beyond the marshmallow level. In spite of the clay. Not because of the pool.
