Prayer for Social Activists

I just learned that the new Reform prayerbook, Mishkan Tefilah, includes the following as an alternative to the strict translation of Mah Tovu:

May the One whose spirit is with us in every righteous deed,
be with all who work for the good of humanity
and bear the burdens of others,
and who give bread to the hungry,
who clothe the naked,
and take the friendless into their homes.
May the work of their hands endure,
and may the seed they sow bring abundant harvest.

It seems like a really good invocation for SFOP meetings and for activists and helpers of every stripe.
