It impossible that God does anything bad

There is a story about a holly saint who lived about hundreds years ago. 

In a town near to the saint, there was a rabbinical college. The students were studying the Talmud and came to the passage that said: "we must thank God for the good as well as the bad." The students were puzzled. Thanking God for the good, that's understandable and reasonable; but thanking God for the bad? That didn't make any sense.

They brought this question to the attention of the dean of the college. He stroked his long beard and pondered the question. "Yes, this is a question that only the saint can answer. Go to his house and ask him!"

The students decided to go immediately. The saint lived outside of the town. They walked beyond the town's limits and entered into the wooded forest. Following a narrow path, they soon arrived at a run-down shack that was the saint's abode. The windows were broken, the roof looked in need of repair and the walls were badly cracked. As the saint greeted them and led them in, they saw the abject poverty in which the saint lived. The chairs were wobbly and few. The other furnishings were shoddy and in poor repair.

The Saint apologized for not having any thing to offer them to eat but perhaps a glass of hot water would be sufficient.

The students explained that they had come to ask him this question. "Why does it say in the Talmud that we must thank God for the good as well as the bad?"

The saint asked them, "Why come to me to ask me that question. I also can not understand it. Nothing bad has ever happened to me. Is it possible that God does anything bad?"
