Ans. The postmaster is rightly depicte representative of God because he managed to collect money for Lencho who was helpless at that time. As God can't be physically present everywhere to help his children, people believe that he relieves their sufferings through his representatives. Here, as that representative is the post master who acts as the epitome of humanity.
When Lencho needed money he had written a letter to god asking for 100 pesos. When the postmaster found out he laughed but eventually decided on helping Lencho. He, using his salary and borrowed little amounts of money from the other employees, collected 70 pesos and put them in an envelope addressing himself as God so that Lencho's faith in God was not broken. When Lencho was in trouble, the postmaster helped him without looking for anything in return. So, in this way the postmaster was a representative of God.
