This line from Ilya Kaminsky reminds me of Till We Have Faces by C. S. Lewis—perhaps the best justification of religion—and also of Lois McMaster Bujold’s philosophical musings on the limits of God/Gods in her Chalion series.  

What question/accusation would you demand of God/Gods? What would they ask/accuse you of in return? What would each’s justification be for the evil in the world? Are the justifications the same? What would each of you do differently? And why can’t either you?
