A saint is a person who practices the keystone human virtue of humility. Humility in the face of wealth and plenty, humility in the face of hatred and violence, humility in the face of strength, humility in the face of your own genius or lack of it, humility in the face of another's humility, humility in the face of love and beauty, humility in the face of pain and death. Saints are driven to humbling themselves before all the splendor and horror of the world because they perceive there to be something divine in it pulsing and alive beneath the hard dead surface of material things -- greater and purer than they are.
When we grow radishes in a small container in a city apartment, we participate in creation. We sustain the globe. When we sweep the street in front of a house in the dirtiest city in the country, we bring new order to the universe. We tidy the Garden of Eden. We make God's world new again. When we repair what has been broken or paint what is old or give away what we have earned that is above and beyond our own sustenance, we stoop down and scoop up the earth and breathe into it new life again, as God did one morning in time only to watch it unfold, unfold, and unfold through the ages.
