President Lincoln's Prayer Before Gettysburg

"…oppressed by the gravity of our affairs, I went to my room one day and locked the door and got down on my knees before almighty God and prayed to Him mightily for victory at Gettysburg. I told Him that this war was His, and our cause His cause, but we could not stand another Fredricksburg or Chancellorsville. Then and there I made a solemn vow to almighty God that if He would stand by our boys at Gettysburg, I would stand by Him. And after that, I don't know how it was, and I cannot explain it, soon a sweet comfort crept into my soul. The feeling came that God had taken the whole business into His own hands, and that things would go right at Gettysburg…" from Abraham Lincoln: The Man & His Faith by G. Frederick Owen
