Be sure of your call to every business you go about. Though it is the least business, be sure of your call to it; then, whatever you meet with, you may quiet your heart with this: I know I am where God would have me. Nothing in the world will quiet the heart so much as this: when I meet with any cross, I know I am where God would have me, in my place and calling; I am about the work that God has set me.
