How can we ensure that these dead would not have died in vain?And how can we make sure that this nation shall have a new birth of freedom and that government of the people, by the people, for the people, shall not perish from the earth?I don’t know about you, but personally, I think it's by being devoted to the same cause to which they gave their last full measure of devotion- by being dedicated to the proposition that all men are created equal.
