Rebbe Nachman of Breslev told his students and followers that before Moshiach comes, the tests of faith would be very difficult. He therefore instructed them to stick together in unity. Finally, he said, "The world will be amazed at the love that there will be among you." Guy Tzvi Mintz put these beautiful words to song, which he sang during Melava Malka at my home this past Motzaei Shabbat (Saturday night). Enjoy!
