This is a reprint of a paywalled Wall Street Journal article, for which I’m grateful. (I hate signing into sites!) This talks about a small pocket devotional Lincoln had, and how it might have influenced some of his writing.
In 1852, when Abraham Lincoln was a railway lawyer with an uncertain future, the Religious Tract Society of London published “The Believer’s Daily Treasure.” Small enough to fit in the palm of your hand, this vest wallet arranged scripts from Scripture every day of the year. The 366 short passengers, including one for leap years, came straight from the King James Bible.
