Here is the prophet's description of the Jewish people:

Your people are all righteous. They will inherit the land forever. They are the shoot of My planting, the work of My hands, in which I take pride. (Isaiah 60:21. Haftarah of Ki Tavo)

Here is it's inner meaning:

We are like the work of a artisan's hands. As a craft satisfies the eye of its artisan, so we are here to fulfill the will of our Creator.

But we are more than a successful project. We are also the shoot of His planting, a catalyst for great change beyond expectations.

As a tiny acorn decomposing in the earth is the catalyst for a giant oak to form from the carbon in the air, so too our souls, planted in this earthly world, take this world far beyond what it was created to be.

And if you ask: How could anything do better than G‑d made it to be?

The answer is that He created the heavens to shine with divine light and an earthly world to hide that light, but His secret desire was that all things should shine.

So, like that seed, our souls break all barriers and fuse the two. With every word of Torah we speak, with every mitzvah and kind deed we do, heaven shines from within the earth, and it grows beyond imagination.

Our souls will return once again to this earth when the time will come. And we will live eternal, divine life in this world we have re-created, as the days of the heavens upon the earth.

Reshimot 46.
