“Our Government springs from and was made for the people — not the people for the Government. To them it owes allegiance; from them it must derive its courage, strength, and wisdom.”

Context: Political parties exist to secure responsible government and to execute the will of the people. From these great tasks both of the old parties have turned aside. Instead of instruments to promote the general welfare they have become the tools of corrupt interests, which use them impartially to serve their selfish purposes. Behind the ostensible government sits enthroned an invisible government owing no allegiance and acknowledging no responsibility to the people. To destroy this invisible government, to dissolve the unholy alliance between corrupt business and corrupt politics, is the first task of the statesmanship of the day.

First Inaugural Address (4 March 1885).
Context: Amid the din of party strife the people's choice was made, but its attendant circumstances have demonstrated anew the strength and safety of a government by the people. In each succeeding year it more clearly appears that our democratic principle needs no apology, and that in its fearless and faithful application is to be found the surest guaranty of good government.
But the best results in the operation of a government wherein every citizen has a share largely depend upon a proper limitation of purely partisan zeal and effort and a correct appreciation of the time when the heat of the partisan should be merged in the patriotism of the citizen.

This quote is incorrectly quoted from Lincoln's Address to Congress on July 4, 1861 http://millercenter.org/president/speeches/detail/3508, in which Lincoln outlined the events that had led to the American Civil War and his views on the nature of the rebellion by the southern slave states. To suppress the rebellion Lincoln said that Congress must "give the legal means for making this contest a short and a decisive one; that you place at the control of the Government for the work at least 400,000 men and $400,000,000." And Lincoln remarked further: "A right result at this time will be worth more to the world than ten times the men and ten times the money. The evidence reaching us from the country leaves no doubt that the material for the work is abundant, and that it needs only the hand of legislation to give it legal sanction and the hand of the Executive to give it practical shape and efficiency. One of the greatest perplexities of the Government is to avoid receiving troops faster than it can provide for them. In a word, the people will save their Government if the Government itself will do its part only indifferently well".
