Which sentence best supports the idea that a government has an obligation to provide certain things to its citizens? from "Message to the Congress in Special Session, July 4, 1861"
by Abraham Lincoln

This is essentially a People's contest. On the side of the Union, it is a struggle for maintaining in the world, that form, and substance of government, whose leading object is, to elevate the condition of men—to lift artificial weights from all shoulders—to clear the paths of laudable pursuit for all—to afford all, an unfettered start, and a fair chance, in the race of life. Yielding to partial, and temporary departures, from necessity, this is the leading object of the government for whose existence we contend.
I am most happy to believe that the plain people understand, and appreciate this. It is worthy of note, that while in this, the government's hour of trial, large numbers of those in the Army and Navy, who have been favored with the offices, have resigned, and proved false to the hand which had pampered them, not one common soldier, or common sailor is known to have deserted his flag.
Great honor is due to those officers who remain true, despite the example of their treacherous associates; but the greatest honor, and most important fact of all, is the unanimous firmness of the common soldiers, and common sailors. To the last man, so far as known, they have successfully resisted the traitorous efforts of those, whose commands, but an hour before, they obeyed as absolute law. This is the patriotic instinct of the plain people. They understand, without an argument, that destroying the government, which was made by Washington, means no good to them.
Our popular government has often been called an experiment. Two points in it, our people have already settled—the successful establishing, and the successful administering of it. One still remains—its successful maintenance against a formidable [internal] attempt to overthrow it. It is now for them to demonstrate to the world, that those who can fairly carry an election, can also suppress a rebellion—that ballots are the rightful, and peaceful, successors of bullets; and that when ballots have fairly, and constitutionally, decided, there can be no successful appeal, back to bullets; that there can be no successful appeal, except to ballots themselves, at succeeding elections. Such will be a great lesson of peace; teaching men that what they cannot take by an election, neither can they take it by a war—teaching all, the folly of being the beginners of a war.
Lest there be some uneasiness in the minds of candid men, as to what is to be the course of the government, towards the Southern States, after the rebellion shall have been suppressed, the Executive deems it proper to say, it will be his purpose then, as ever, to be guided by the Constitution, and the laws; and that he probably will have no different understanding of the powers, and duties of the Federal government, relatively to the rights of the States, and the people, under the Constitution, than that expressed in the inaugural address.
He desires to preserve the government, that it may be administered for all, as it was administered by the men who made it. Loyal citizens everywhere, have the right to claim this of their government; and the government has no right to withhold, or neglect it. It is not perceived that, in giving it, there is any coercion, any conquest, or any subjugation, in any just sense of those terms.
The Constitution provides, and all the States have accepted the provision, that "The United States shall guarantee to every State in this Union a republican form of government.'' But, if a State may lawfully go out of the Union, having done so, it may also discard the republican form of government; so that to prevent its going out, is an indispensable means to the end of maintaining the guaranty mentioned; and when an end is lawful and obligatory, the indispensable means to it are also lawful, and obligatory.
