In a similar vein, the Gemara states that some mitzvos will be nullified. Why What is unique about Chanukah and Purim over the other Yamim Tovim? Will there be a need to do teshuvah on Yom Kippur in the future?
In this Geula and Moshiach Shiur, Rabbi Sholom Zirkind explains why Chanukah and Purim will last forever.
