Faith: Lencho had unshakeable faith in God. When the hailstorm destroyed his crops, he wrote a letter directly to God asking for 100 pesos. When he received 70 pesos, he showed no surprise — such was his unwavering confidence that God would help him. He immediately wrote a second letter requesting the remaining amount, proving his blind, absolute trust in God.
Irony: The irony lies in the fact that the very people — the post office employees — who collected money out of charity and kindness to strengthen Lencho's faith, are called "a bunch of crooks" by Lencho himself in his second letter. The ones who helped him became the suspects in his eyes.
