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.
God who loves us knows us. We long to be known, not only from the outside but from within. We feel that if others knew us as we really are, with our hopes, dreams and struggles to be whole, they would have a compassionate and tolerant love for us. Conversely, were we to live for an hour within the mind of another, even that of a social outcast, we would come away humbled and more understanding. We cannot know people from within, only from without and with difficulty despite our love. Not so with God. The Spirit of God has been poured out on us. God has made a home in us.
