“The greater one's purity, the more clearly one sees how much one sins; and the more one sins, the more benighted one is, even though one may appear to be pure. Again, the more knowledge one has, the more one thinks oneself ignorant; and the more one is ignorant of one's ignorance and of the shortcomings in one's spiritual knowledge, the more one thinks one knows. The more the spiritual contestant endures afflictions, the more he will defeat the enemy; and, lastly, the more one tries for one day to do something good, the more one is a debtor all the days of one's life, as St Mark has said; for even if the ability and desire to do good are one's own the grace to do it comes from God. It is only because of this grace that we are able to do anything good; when we do it, then, what have we to boast about?” DesireSinGracePurity Author:St. Peter of Damascus
