One of the effects of original sin is an instinctive prejudice in favour of our own selfish desires. We see things as they are not, because we see them centered on ourselves. Fear, anxiety, greed, ambition and our hopeless need for pleasure all distort the image of reality that is reflected in our minds. Grace does not completely correct this distortion all at once: but it gives us a means of recognizing and allowing for it. And it tells us what we must do to correct it. Sincerity must be bought at a price: the humility to recognize our innumerable errors, and fidelity in tirelessly setting them right.
