“To believe in the things you can see and touch is no belief at all - but to believe in the unseen is a triumph and a blessing.”

“You can fool some of the people all of the time, and all of the people some of the time, but you can’t fool all of the people all of the time.”

“That we here highly resolve that these dead shall not have died in vain; that this nation, under God, shall have a new birth of freedom; and that this government of the people, by the people, for the people, shall not perish from the earth.”

“I am a slow walker, but I never walk back.”

“Today is the tomorrow you worried about yesterday.”

“From whence shall we expect the approach of danger? Shall some trans-Atlantic military giant step the earth and crush us at a blow? Never. All the armies of Europe and Asia...could not by force take a drink from the Ohio River or make a track on the Blue Ridge in the trial of a thousand years. No, if destruction be our lot we must ourselves be its author and finisher. As a nation of free men we will live forever or die by suicide.”

“Four score and seven years ago our fathers brought forth on 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 battlefield of that war. We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead who struggled here have consecrated it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here. It is for us the living rather to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion — that we here highly resolve that these dead shall not have died in vain, that this nation under God 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.” 

“Take all that you can of this book upon reason, and the balance on faith, and you will live and die a happier man. (When a skeptic expressed surprise to see him reading a Bible)”

“If I do good, I feel good...If I do bad, I feel bad”

“Folks are usually about as happy as they make their minds up to be.”

“If Friendship is your weakest point, you are the strongest person in the world.”

“I do the very best I know how—the very best I can; and I mean to keep doing so until the end. If the end brings me out all right, what is said against me won’t amount to anything. If the end brings me out wrong, ten angels swearing I was right would make no difference.”

“A tendancy to melancholy...let it be observed, is a misfortune, not a fault.”

“A house divided against itself cannot stand." I believe this government cannot endure, permanently half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided. It will become all one thing or all the other.”

“Must is the word... You can not fail if you resolutely determine that you will not... Always bear in mind that your resolution to succeed is more important that any other thing.”
