If we make every effort to avoid death of the body, still more should it be our endeavor to avoid death of the soul. There is no obstacle for a man who wants to be saved other than negligence and laziness…

Those who scorn to grasp what is profitable and salutary are considered to be ill. Those, on the other hand, who comprehend the truth but insolently enjoy dispute, have an intelligence that is dead; and their behavior has become brutish. They do not know God and their soul has not been illumined. –St Antony the Great ‘Philokalia’
