Tradition has it that in the wake of the High Holidays, and of Sukkot, one may reach a higher spiritual level on Simchat Torah than even Yom Kippur. One may build on the Yom Kippur fast to achieve more by dancing with the Torah.
Perhaps this is the idea of all my limbs will speak faith in the L-rd. The limbs speak when they move and rejoice when they dance, when every ounce of energy is put into dancing with the Torah, and with fellow Jews. This once-a-year-opportunity culmination of the holiday season is Sunday. Chag Sameach!
