Why does Lincoln still matter?

Why does Lincoln still matter?

Part of the answer still rings true in words by Dr. Stephen E. Ambrose:

"He believed in America, in her Constitution, in her political system, and he believed in them much more deeply than the crititics who shouted "depotism" every time he found it necessary to go outside the law to achieve his purpose. He and Churchill stand alone on the mountain top, for of these two men, and of them only, can it be truly said, Had he not lived his nation would not now be."
