This fragment from “Fear Not of Men” by Mos Def has gotten me through a lot of adversity, most recently in particular when I was being abused by the evil resident during my OBGYN rotation.

All around the world hearts pound with the rhythm
Fear not of men because men must die
Mind over matter and soul before flesh
Angels for the pain keep a record in time
which is passin’ and runnin’ like a caravan freighter
The world is overrun with the wealthy and the wicked
But God is sufficient as disposer of affairs
Gunmen and stockholders try to merit my fear
But God is sufficient over plans they prepared
