“When a new Baal Teshuva dies a sudden, tragic death…people ask, how is this possible?…’Why did Hashem take him so suddenly?’ The most famous question of the perplexed is: ‘What about the Holocaust…?’
People forget that this world is a place of temporary significance at best, where a soul assumes a bodily form to perform a mission and achieve a needed tikkun. But, if they’d remember that the life and health of the soul is our primary concern — and not the body — then their questions would fall by the wayside.” ~ The Garden of Emuna

very difficult. human suffering is hard to deny or overlook. needs deep faith. unfortunately, not attainable by most, or any maybe
No one is claiming that it is not sad when someone dies. These things are all tragic and we mourn for them. However, I think the point is, we should not question Hashem’s ways. Once we acknowledge that everything happens for a reason, we won’t question Hashem.
