In the 30's depression, Winter Shakers were people who pretended faith to gain shelter and food in the winter. The lyrics seem to bear out the meaning:
"clap my dirty hands" = dirt as a symbol for both poverty and the speaker's deceit
"living on Indian land" = living off misappropriated goods
"deep devotion at the bottom of the sea" = devotion as a refuge of those already drowned in misery
"iniquity does down like water" = gross injustice becoming so normalised it becomes a natural part of survival
"spoken behind the hand" = as if lying, or fearful that the proclamations of GO's grace, "all his glory", are in fact in any way sincere
"It is the storm that brought me in" = the personal misfortune that made the speaker desperate enough to proclaim rabid faith in an attempt to gain shelter
