Few are saved. Why? Because of the gravity of sin. Even more grievous for Catholics because despite Gods grace (mass, the sacraments), they sin as they do and think nothing of it. They are filthy with sin, they are playing around in mud, and they think that they are clean ("good") because they see the world playing around in manure sludge.
St. Francis said that as God is the Light, as we come closer to him, it is as if we bring a light closer and closer to us. When we look at ourselves in the mirror, the less light we have, the less imperfections we see, the more perfect we think we are. As we add (receive) more light, we begin to see more and more of our imperfections, wrinkles, scars, pimples, pores. We are blind as to what we really are. When St. Francis died, he was convinced that he deserved Hell, and entrusted himself to God’s Mercy. He knew that he was not clean because he had been so close to God. ST. FRANCIS OF ASSISI!
