Shortly after arriving at the Keller household, Annie Sullivan wrote, "I am convinced that obedience is the gateway by which knowledge, yes and even love, enter the mind of the child." With this remarkable insight, Sullivan had the courage to teach Helen to obey - to sit at the table, to eat properly, to fold her napkin. It was by first learning obedience that Helen learned the concept of language and also grew to love her teacher.

Annie Sullivan's words speak to us as we reflect on Zechariah's and Mary's questions. "Obedience is the gateway by which knowledge, yes and love, enter" our minds. It is in acts of obedience that we grow in the knowledge and love of God.
