What is the main idea of this excerpt of Abraham Lincoln's Second Inaugural Address?

Lincoln's speech was an effort to answer this question, as well as an attempt to reach out to what he called his "dissatisfied fellow-countrymen" in an effort to avoid the coming conflict. He had held to a strict policy of silence during the months leading up to his inauguration, carefully avoiding making any statements that could be misconstrued by either North or South, prior to becoming the legal leader of the nation. Lincoln's intention was that no statement of his specific policy toward the South should be made available before he had taken office. Those privy to the speech's possible contents were sworn to silence, and Lincoln's draft was kept locked in the safe of the Illinois State Journal newspaper.
