In The Miracle Worker, how is Annie Sullivan like Christ in her relationship with Helen Keller?

Annie Sullivan in The Miracle Worker did something that others thought was impossible.  She helped Helen Keller to "see" the world through words and language.  The play is called The Miracle Worker because Annie transformed Helen's entire life in a way that was like a miracle.  Annie taught Helen that every object and thing in life has a name.  She taught her the names of these things by spelling into her hand.

In the Bible, Jesus Christ healed a man who had been born blind.  Jesus created a mixture of mud and His own saliva and placed it on the man's eyes.  He then spoke to the blind man and instructed him to go "wash in the Pool of Siloam."  The blind man followed the instructions.  When he came out of the water, he could see again.  

In this story, Jesus performed a literal miracle by giving a blind man sight.  In The Miracle Worker, Annie performed a figurative miracle by giving Helen the gift of knowledge about the world around her.

In the Bible, Jesus was known as a teacher.  He taught people through parables and instructions.  He also was a companion to His disciples and close followers.  In The Miracle Worker, Annie was a teacher to Helen.  She was also a friend and companion to her.
