What is written in a Gemara is not Nistaros. Let’s also not forget the actual meaning of that Pasuk, which is that we can not be responsible for what people think, only for what they do and say. Using that Pasuk to discourage some people from learning certain areas of the Torah when they are not ready for it, is cute and even a worthwhile cause. It is not the actual meaning of the Pasuk, however, that it can be applied to normative Mesorah on standard topics.
The Gemara in Shabbos 31 says,
??? ??? ???? ???????? ??? ???? ?????? ?? ???? ???? ?????? ???? ???? ????? ???? ???”? ???? ?????? ????? ????? ???? ??? ???? ??? ???”? ?? ???? ?’ ??? ????? ??? ?? ?? ??
It’s a Mitzva, and it seems to come before advanced learning.
kkls,
There is a set deadline for Moshiach whether we deserve it or ?”? not. If we are Zoche then he will come before the latest deadline. If we are Zoche then Moshiach ben Yosef will live. If we are Zoche then Moshiach will come riding high. This deadline has to be before the year 6,000 since that is the end of the world. The concept of the world starting over is mentioned in the Rishonim but is not related to Moshiach. Moshiach will come, no matter what.
May it be the will of Hashem that we all merit to greet Moshiach very soon.
