The 2nd one is the correct answer based on the question's topic
Eternal Life. The idea is that a person's soul will be redeemed by the sacrifice of Christ and saved from punishment in hell. The idea is that your soul will live on after the death of the body, and eventually you will be judged. If you are judged as a christian, you are saved from eternal punishment in hell and are given a new body with which to live in in a perfect world. The beliefs vary slightly depending on the denomination, but that it the main idea.
That's an interpretive question that would ask us to get inside the mind of Lincoln from a distance a century and a half away. We do know that Lincoln long had moral and political objections to slavery. He had outlined some of those thoughts in a speech given in Peoria, Illinois, in 1854. But Lincoln's views on what to do about slavery were something that took shape over time. In the Peoria speech, he suggested that perhaps slaves should be freed in order to be returned to Africa. But as the conflict over slavery grew and the Civil War became a reality, Lincoln became firmer in seeing this as a struggle not just over preserving the Union but also a battle for human dignity and the principle of equality. And so in the Gettysburg Address, in 1863, he affirmed the principle stated by the Declaration of Independence, that all men are created equal. The massive number of casualties at the Battle of Gettysburg certainly gave impetus to Lincoln's words about preserving the Union and government of the people, by the people and for the people. But those ideas had been central to Lincoln's worldview before Gettysburg as well as in that speech.
