Answer:
<em>"87 years ago, our parents gave birth on this continent to a new nation, conceived in Liberty and consecrated to the principle that all men are born equal."</em>
Explanation:
As you may already know, the declaration of independence proclaimed the birth of a sovereign and free nation. In this new nation, freedom would be a right for all people, whether born there or looking for that nation as a home, that could offer them the equality that their home nation did not offer.
In his speech, Lincoln wished to recall the concept of freedom advocated in the Declaration of Independence. This can be seen in the excerpt:
<em>"87 years ago, our parents gave birth on this continent to a new nation, conceived in Liberty and consecrated to the principle that all men are born equal."</em>
