"Isaiah himself was a prophet of challenge and stern demand. He set high standards, conceived brave ideals, aimed at goals beyond the wider human reach. If you hear him you grow confused because he upsets your notions, if you go with him you run into trouble because you are pushing against the crowd, if you deny him you feel guilty because you know he is right. Ignorance of the prophet Isaiah is the safer way, and the prudent reader will skip the next few pages of this chapter – unless, of course, he has already made Isaiah’s acquaintance, under which circumstance there is no more help for him."
