Worship in Washington

One book that carries a version of this story is Twenty Days (p. 137). Twenty Days does not have footnotes, so I do not know the source. If anyone knows the story's source, please post! Thanks.

The earliest source I could fine is "The Inner Life of Abraham Lincoln: Six Months At the White House" by F B Carpenter (!866)
It can also found in "Abraham Lincoln: From Skeptic to Prophet", by Wayne Temple and "The Religion of Abraham Lincoln" or "The Almost Chosen People" by William J Wolf
