The Midrash goes on to explain why Yitzchak resembled Avraham.
Rumors circulated that Sarah became pregnant from Avimelech. To
prevent any aspersion on Yitzchak’s genealogy, Hashem made Yitzchak’s
countenance mirror Avraham’s.
On the day that Yitzchak was weaned, Avraham invited Avimelech along
with other kings and leaders to a festive meal. Why? Wouldn’t this only
lead to more gossip? The complete resemblance between Yitzchak and
Avraham left behind no doubt. Every observer could see that Yitzchak
was Avraham’s son merely by looking at him.
Why did Hashem arrange Sarah’s abduction to Avimelech’s palace shortly
before her pregnancy with Yitzchak? Didn’t it just arouse speculation?
The Palestinians claim to be the original owners of the Land. They bolster
their claim by pointing at the obscurity of the Divine plan and the
anonymity of its main characters. How do we fight such claims?
Hashem put the Palestinians in this land and gave them prior jurisdiction
for this very purpose. He wants to see us walk in His ways. By acting as
the spiritual heirs of the Patriarchs, we demonstrate our similarity to the
Avot. It is this similarity which disproves the claims of the Palestinians.

“Rather, to my land and to my kindred shall you
go and take a wife for my son, for Yitzchak”

(Bereishit 24:4)
