As a watchmaker with his glasses distinguishes the most minute wheels of a watch, so we, with the light of the Holy Ghost, distinguish all the details of our poor life. Then the smallest imperfections appear very great, the least sins inspire us with horror. That is the reason why the most Holy Virgin never sinned. The Holy Ghost made her understand the hideousness of sin; she shuddered with terror at the least fault.
--St. Jean Vianney, the Cure of Ars
