Chasidut su Isaia 60:21

Indeed, from the moment of creation and onward, God desired that man receive reward based upon his own efforts and (what the psalmist calls) “the work of his hands.” This is as it is said in the Midrash,²⁷Midrash Kohelet, 4:6, on the verse, “Better a handful of quietness, than two fistfuls of labor and striving after the wind.” “Man’s efforts are called striving – and then eating.” For this reason man was given free choice. This is as it is written in the Tikunei Zohar (70, page 137b): When the Torah says, “let us make a man,” it means that man needs to fulfill the commandments of the Torah, and exert himself in the Torah, “to work it and to guard it.” From this he will be rewarded and gain mastery over the angels. This is (Yeshayahu, 60), “the bud of My planting, the work of My hands in which to glory.” We find that although the supernal angels are mighty in strength and perform God’s word, still they are not mighty in the service of the Holy One, blessed be He. This is because they are forced to serve Him, and face no obstacles like the physical body or the evil inclination.... For this reason it is said, “let us make a man (who overcomes these obstacles by using his power of choice, to serve God out of his own volition).” For this reason man will rule over the angels.

Isaiah proclaims, Ve-ammeich kullam tzaddikim, “[Members of] Your nation are all righteous” (Isa. 60:21). This verse is also understandable in the light of yechidah. Since every Jew at his or her deepest level wants to serve God, from that perspective he or she never wanted to perform any sins and is completely saintly. Based on yechidah, all of Jewry is guaranteed a portion of eternal reward united in the perfect fellowship of pure virtue and total observance.²¹⁰See further Sanhedrin 90a.
