An Environmental Parable

The Kingdom of God is like water on concrete. At first glance it seems that concrete and asphalt ought to have the upper hand. Water, at least in small portions, cannot overcome the pavement. But water does it's work quietly. It runs along casually finding the cracks and crevices and weak spots in cement, and the Spirit of God blows his fierce frosty air over the waters causing them to freeze and expand, and the concrete cannot withstand the pressure. Asphalt crumbles, pavement cracks and breaks apart, potholes appear, and hard heart after hard heart is burst into pieces by the water and the Spirit.
