Everything is for the good of Israel!

Shelah Hakadosh, Parashas Balak

Know that there is no evil that descends from above for the nation of Israel, because they are the children of Hashem. If there is a situation of "Hashem's anger will flare" on them in the destructions of the Mikdashes and the destruction of Israel in their exile amongst the nations--everything is for their benefit. In the way that a man straightens the path of his son, so does Hashem straighten our path, and everything is for our good, to be purified in the crucible of the nations, to remove our sins, and to be completely refined without any sediment, without and dross--only radiant light for the time to come--because the sufferings cleanse us and also bring us to tshuva.
