In the Footsteps of Avraham

IN class, we came up with many possibilities about why Yitzchak did many of the same things as Avraham. One of the ideas we came up with ( with the help of the article by Rav Amnon Bazak ) was that he was not the trailblazer that father was. He was not as active, as we learned earlier in the year. BY repeating the actions of his father, he was "cementing" the actions of his father so others could easier find the path. Another idea we came up with that he had a special connection to the land so he did not leave it. It could also be necessary to show us that YItzchak was worthy of receiving the promise of Avraham.
