Yiddishkiet as a whole doesn’t need it but non frum people need it. There are many incredible stories from Bale Teshuvah that experienced miracles (probably in the zchus of their holy forebears) which lead them to search into their Judaism and become frum. These people often need that something to push them to wake them up and realize that there’s a Hashem and an Oilum Habah.
