Rabbi Yehoshua Magnes: 'Eretz Israel and the story of the Haggadah'

The Haggadah traces the development of the Jewish People from an extended family to the nation that sets the moral code for mankind.

Eretz Yisrael, however, is not a central part of the story of the Haggadah. That is understandable, as the entrance to the land happened forty years later - a lifespan after the Exodus. 

A  new generation and a new leader entered the Promised Land.  

So what is the connection between the Exodus and Eretz Yisrael?
