“The will of God prevails. In great contests each party claims to act in accordance with the will of God. Both *may* be, and one *must* be, wrong. God cannot be *for* and *against* the same thing at the same time. In the present civil war it is quite possible that God's purpose is something different from the purpose of either party - and yet the human instrumentalities, working just as they do, are of the best adaption to effect His purpose. I am almost ready to say that this is probably true - that God wills this contest, and wills that it shall not end yet. By His mere great power, on the minds of the now contestants, He could have either *saved* or *destroyed* the Union without human contest. Yet the contest began, And, having begun He could give the final victory to either side any day. Yet the contest proceeds.”

“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.”
