Did Lencho try to find out who had sent the money to him? Why/Why not?
No, Lencho did not try to find out who had sent the money to him. He was fully convinced that the money was sent by God himself.
Lencho had complete faith in God. When he received the letter with the money, he showed not the slightest surprise. Such was his confidence that he never doubted the source of the money for a moment. He firmly believed that God had answered his prayer and sent the hundred pesos he had asked for.
His unshakable faith is further evident when he counted the money and became angry. He believed that God could not have made a mistake, nor could he have denied Lencho what he had requested. He did not even consider the possibility that someone else might have sent the money.
Instead of questioning God, when he found only a little more than half the amount, he suspected the post office employees. He called them a bunch of crooks in his second letter, believing they had stolen the rest of the money. Thus, his blind faith in God prevented him from discovering the true senders.
Explanation
The textbook highlights Lencho's extraordinary, unwavering faith in God. Because he had absolute certainty that God would answer his letter and send the money, he felt no need to investigate who actually sent it. His lack of surprise upon receiving the money and his anger at the shortfall (believing God could not make a mistake) reinforce this. The irony, as noted in the textbook's questions, is that the very employees he accused of being crooks were the ones who charitably gathered the money for him.
