This posuk may be explained in a novel way. Even if one will sink so low in pursuit of gratifying his physical and material desires, thus distancing himself further and further from Hashem, there is still hope for his return. As long as “those that are dispersed” are still “in the uttermost parts of heaven“, they still maintain a thin spiritual link, however flimsy and remote; a spark which can still be stoked, then Hashem will gather them and take them back. The spark of a “yiddishe neshoma” cannot be extinguished.
