If any of you are dispersed at the outermost parts of heaven

If any of you are dispersed at the outermost parts of heaven, from there will the L-rd your G-d gather you (Deut. 30:4)

No matter how far a Jew may be from Torah and Judaism, G-d promises to gather him back into the fold of the Jewish people when Moshiach comes. When a Jew is spiritually brought back from "the outermost parts of heaven," it hastens Moshiach's coming and brings the Redemption closer. (Lubavitcher Rebbe, shlita)
