Isaiah 58 is an indictment of those who would embrace religion and spirituality, but not their neighbor. The chapter begins a bit harshly, but the prophet’s fire is meant to turn us toward blessing, plenty, and peace. Want to do some real fasting? Give your food to the hungry, shelter the homeless, stop exploiting workers, enough with the pointing finger and the strife. Fast from injustice and spend your days smashing every yoke and lifting every burden as if proper observance of the Sabbath demanded it. Because it does.
