Why does the postmaster send money to Lencho? Why does he sign the letter 'God'?
The postmaster sends money to Lencho because he is deeply moved by the farmer's immense faith in God. When he reads the letter addressed to God, he initially laughs but quickly turns serious, wishing he had the same faith.
He decides that he must not shake the writer's faith in God. To fulfill this resolution, he asks for money from his employees, gives part of his own salary, and convinces friends to contribute for an act of charity. Although he cannot gather the full hundred pesos, he sends a little more than half.
The postmaster signs the letter as 'God' to maintain the illusion that the money was actually sent by the Almighty. Since Lencho had written directly to God, any other signature would have revealed the truth and broken his trust.
By using this single-word signature, the postmaster successfully preserves Lencho's unshakable confidence in God. This selfless act gives the postmaster the deep contentment of a man who has performed a truly good deed.
Explanation
The postmaster is struck by Lencho's extraordinary faith when he sees the letter addressed to God. To prevent this faith from being shattered, he takes it upon himself to collect the requested money as an act of charity. Signing the letter as 'God' is a deliberate choice to maintain the illusion of divine intervention, giving the postmaster the contentment of performing a good deed while keeping Lencho's belief alive. Ironically, Lencho's faith is so absolute that he never questions the signature, instead blaming the post office employees for the missing money.
