The postmaster sends money to Lencho because he is deeply moved and impressed by Lencho's strong faith in God. Lencho, a poor farmer, had written a letter to God asking for financial help after a hailstorm destroyed his crops. The postmaster, moved by the sincerity and unwavering faith exhibited in the letter, decides to help Lencho by collecting money from his colleagues and himself to support Lencho and his family. The postmaster signs the letter as "God" to avoid shaking Lencho's faith in divine intervention. He wants Lencho to believe that his prayers were answered by God directly and to preserve his strong belief in God's help. This gesture is also meant as a kind and thoughtful way to maintain Lencho's hope and trust in God during difficult times.
