Musar zu Jeschijahu 51:18

And the prophet further said: "She has none to guide her out of all the sons she bore, none takes her hand of all the sons she raised" (Yeshaya 51:18). And "all flesh is grass, and all his kindness is as the blossom of the field" (Isaiah 40:6), which our sages of blessed memory, explained: "all the kindness they do is only for themselves" (Zohar Chadash 117a, Tikunei Zohar 30,63a), i.e. for their own good and benefit; they do not intend for this perfect intention and do not seek the raising of G-d's honor and the redemption of Israel.

For it is impossible for the honor of G-d to be raised except through the redemption of Israel and the raising of Israel's honor, since in truth, one depends on the other, as the prophet said in Tana D'Bei Eliyahu I mentioned: "and he grieves over the honor of the Holy One, blessed be He, and over the honor of Israel".
