I have heard that when the moshiach comes, we won’t be obligated to keep the mitzvoth. If this is so, how does this not go against the Torah? I mean the Torah says that we will always keep the mitzvoth forever, and this idea states that we will not have to keep the mitzvoth, which is seems clearly against the Torah.
Here's my personal understanding of this topic:
- The Messianic era mentioned everywhere spans a very long time, with numerous stages and transformations. It is not a single occasion of appearing of the Messiah (see Rambam Melachim-uMilchamot-Chapter-11). Therefore we don't talk about cancellation or abandoning of the Mitzvot but rather switching to a different reality.
- A possible explanation would be the lack of the evil inclination (Yetzer Harah), without which there's no meaning for commandments, as therefore no choice (similar to the YT video above). This is also called the clarity of the reality of Hashem.
- In addition, the Mitzvot are given in order to raise ourselves to a higher spiritual level (personally and globally), in Messianic times that level will be finally reached and the Mitzvos (as tools) will become unneeded.
- To some Poskim (Ramba"n?) the Messianic era eventually leads to a spiritual, non physical world, in which performing physical Mitzvot also does not make sense.
- Torah's understanding is subject to interpretations. The Messianic era is not mentioned or discussed in it, and it leads to different approaches to it.
