Question

Hello!
I read the following quote by Leo Strauss:
“Our past, our heritage, our origin, are not a disaster, as Heine said, and still less a disgrace, but suffering—heroic suffering, suffering that stems from the heroic act of self-sacrifice by an entire people for something that seemed to it immeasurably exalted, and in fact infinitely exalted. No Jew today could do himself a greater favor than to live with the memory of the past.”

And I wanted to ask: is suffering, in and of itself, part of Judaism?
I don’t understand this very well, but I know that in Christianity suffering is a central part of atoning for sins.
Is suffering / enduring suffering also a value in Judaism in itself, or is it simply a side effect of Jewish history as a distinct and persecuted people?
