Which statement best describes how Lincoln develops the theme that the North and South, while at war, are more alike than they realize? He illustrates that once the North wins the war, the country will finally be united again under a new order. He declares that while they have been at war, both the North and South pray to the same God; this is meant to reinforce the idea that they are all Americans and hold the same values. He declares that the war has destroyed many on both sides of the conflict. Because they have both suffered so much, they are united in grief. Nothing else matters. He reinforces the just cause of the North by citing God’s approval for the war and their victory.
