Which sentence in the gettysburg address supports the claim that president lincoln did not recognize the historical importance of his speech?

(four score and seven years ago our fathers brought forth, upon this continent, a new nation, conceived in liberty, and dedicated to the proposition that "all men are created equal.")
now we are engaged in a great civil war, testing whether that nation, or any nation so conceived, and so dedicated, can long endure. we are met on a great battle field of that war. we have come to dedicate a portion of it, as a final resting place for those who died here, that the nation might live. this we may, in all propriety do.
(but, in a larger sense, we can not dedicate—we can not consecrate—we can not hallow, this ground)—the brave men, living and dead, who struggled here, have hallowed it, far above our poor power to add or detract.
(the world will little note, nor long remember what we say here; while it can never forget what they did here.)
(it is rather for us, the living, we here be dedicated to the great task remaining before us—that, from these honored dead we take increased devotion to that cause for which they here, gave the last full measure of devotion)—that we here highly resolve these dead shall not have died in vain; that the nation, shall have a new birth of freedom, and that government of the people by the people for the people, shall not perish from the earth.

Which sentence in this excerpt from leo tolstoy’s the death of ivan ilyich shows the human tendency to contemplate one’s past life? "but if that is so," he said to himself, "and i am leaving this life with the consciousness that i have lost all that was given me and it is impossible to rectify it—what then? " he lay on his back and began to pass his life in review in quite a new way. in the morning when he saw first his footman, then his wife, then his daughter, and then the doctor, their every word and movement confirmed to him the awful truth that had been revealed to him during the night. in them he saw himself—all that for which he had lived—and saw clearly that it was not real at all, but a terrible and huge deception which had hidden both life and death. this consciousness intensified his physical suffering tenfold. he groaned and tossed about, and pulled at his clothing which choked and stifled him. and he hated them on that account. he was given a large dose of opium and became unconscious, but at noon his sufferings began again. he drove everybody away and tossed from side to side. his wife came to him and said: "jean, my dear, do this for me. it can't do any harm and often . healthy people often do it." he opened his eyes wide. "what? take communion? why? it's unnecessary! " she began to cry. "yes, do, my dear. i'll send for our priest. he is such a nice man." "all right. very well," he muttered. when the priest came and heard his confession, ivan ilyich was softened and seemed to feel a relief from his doubts and consequently from his sufferings, and for a moment there came a ray of hope. he again began to think of the vermiform appendix and the possibility of correcting it. he received the sacrament with tears in his eyes.
