Why did Jewish people keep letting their lives go back to normal even though horrible things were happening?

Some didn't have much of a choice in the matter because most Jewish people during terror attacks or war breakouts were poor and others beveled or believe that god would or will not let there city fall to ruins i choose not to go too deep into religious thing like that

Because they believed that God wouldn’t let anything happen to them (at least most of them)

So their faith was so strong that they weren’t afraid of what was happening
