Instead of saying there are signs that the arrival of Moshiach is imminent, I’d rather say there are signs that the redemption of the Jewish people seems to be under way:
1. After 2,000 years of exile, we are witnessing the return of the Jewish people to the land of Israel – probably the biggest sign of all.
2. The mitzvos are starting to be returned to us, as is evident with the re-emergence of the chilazon and techeiles (yes, I do wear it, especially for this reason).
Remember that the arrival of Moshiach is much more than a person riding up on a donkey and blowing a shofar – it is the redemption of the Jewish people followed by the redemption of humanity.
For me personally, when I think about these happenings, I have a lot more feeling when saying “Ani Ma’amin” – because it seems clearer by the day that Moshiach can arrive at any moment.
