“ I remembered Robyn telling me the story of Shadrach, Meshach, and Abednego, and how they'd survived: when the King chucked them in the furnace and an angel or someone went in with them. The furnace blazed all around them but they didn't burn.And it did calm me. I don't know if it was Robyn or an angel or even God himself was in the boot, but I was starting to suspect that whenever I wanted God, he was there. Only not necessarily in the form I wanted, or doing what I wanted...In the pitch of the black boot I clung to the image of a fiery furnace, and it wasn't the furnace or Hell either. ”
