Who gave Jews hope during troubled times all must work for a just society?

Many figures throughout history have inspired hope among Jews during troubled times, notably leaders like Rabbi Abraham Joshua Heschel, who advocated for social justice and civil rights in the 20th century. His teachings emphasized the importance of working towards a just society, urging individuals to engage in activism for the betterment of all. Additionally, the concept of Tikkun Olam, or "repairing the world," is a central tenet in Judaism that encourages communal responsibility and hope for a more equitable society. These ideals collectively foster resilience and motivation among Jewish communities during challenging periods.
