Salt is a preservative. Salt adds flavor. Salt melts ice, and perhaps even ice-cold hearts. The church as salt is humming along, caring for its own. Parishioners feel valued and appreciated.
People watch the parish children grow up.
There are births, weddings, funerals, and gatherings of all kinds. It's very easy for a parish, and for a person to stay sitting in salt, just like salt in the jump rope game. You can even reuse salt, to a point. If salt is recycled over and over again, used to flavor food or to help with boiling, eventually it looses its taste. Then, the best thing for salt is to throw it on the ground to cut down on dust.
