One minute Moses is the canonical author of the Pentateuch, the next he’s a guy who keeps knocking Hopeful down. But the book is always psychologically realistic, to an extreme degree. No one knew anxiety and terror better than Bunyan did, and when Christian is passing through the Valley of the Shadow of Death and hears voices whispering blasphemies in his ears, the true horror of the moment is that he thinks he himself is uttering the blasphemies.
