First Debate with Stephen Douglas in the Lincoln-Douglas debates http://www.bartleby.com/251/ of the 1858 campaign for the U.S. Senate, at Ottawa, Illinois (21 August 1858). Lincoln later quoted himself and repeated this statement in his first Inaugural Address (4 March 1861) to emphasize that any acts of secession were over-reactions to his election. During the war which followed his election he eventually declared the Emancipation Proclamation, freeing the slaves in those states in rebellion against the union, arguably as a war measure rather than as an entirely political or moral initiative.

This anecdote apparently dates from 1864 Massachusetts Sunday School Teachers' Convention.
This has been portrayed to have been Lincoln's "reply" to an unnamed Illinois clergyman when asked if he loved Jesus, as quoted in The Lincoln Memorial Album — Immortelles (1882) edited by Osborn H. Oldroyd [New York: G.W. Carleton & Co. p. 366 http://books.google.com/books?id=pX5DEhCM9M0C&pg=RA10-PA366&lpg=RA10-PA366&dq=%22and+saw+the+graves+of+thousands+of+our+soldiers%22&source=web&ots=Alddnu8KL8&sig=IhhhPHp6tuB7FoiRI8c71w5NUH4#PRA10-PA365,M1
This incident must have appeared in print immediately after Lincoln's death, for I find it quoted in memorial addresses of May, 1865. Mr Oldroyd has endeavored to learn for me in what paper he found it and on whose authority it rests, but without result. He does not remember where he found it. It is inherently improbable, and rests on no adequate testimony. It ought to be wholly disregarded. The earliest reference I have found to the story in which Lincoln is alleged to have said to an unnamed Illinois minister, "I do love Jesus" is in a sermon preached in the Baptist Church of Oshkosh, Wisconsin, April 19, 1865, by Rev. W. W. Whitcomb, which was published in the Oshkosh Northwestern, April 21, 1865, and in 1907 issued in pamphlet form by John E. Burton.

In this famous statement, Lincoln is quoting the response of Jesus Christ to those who accused him of being able to cast out devils because he was empowered by the Prince of devils, recorded in Matthew 12:25: "And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand".

Context: My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union.

Repentance before forgiveness is a provision of the Christian system, and on that condition alone will the Republicans grant his forgiveness.
