The physical force of gravity pulls everything to the center of the earth. In order to break free from earth-centered life, thousands and thousands of pounds of energy have to push the space shuttle away from the center. There is also a psychological force of gravity that constantly pulls our thoughts and affections and physical actions inward toward the center of our own selves and our own homes.
Therefore the most natural thing in the world is to neglect hospitality. It is the path of least resistance. All we have to do is yield to the natural gravity of our self-centered life, and the result will be a life so full of self that there is no room for hospitality. We will forget about it. And we will neglect it. So the Bible bluntly says. Stop that! Build a launching pad. Fill up your boosters. And blast out of your self-oriented routine. Stop neglecting hospitality. Practice hospitality.
