But Lincoln certainly read the Bible and read it well. Lots of eyewitness accounts say so. More important, his rhetoric often drew from it in both obvious and subtle ways. One of his best-known lines—“a house divided against itself cannot stand”—is a plain reference to Mark 3:25 and Matthew 12:25. The famous opening words of the Gettysburg Address—“Four score and seven years ago”—echo Psalm 90:10. To explain the connection between the principles of the Declaration of Independence and the framework of the Constitution, Lincoln turned to Proverbs 25:11: “A word fitly spoken is like apples of gold in pictures of silver.” He meant that the purpose of the Constitution is to preserve the ideas in the Declaration.
Lincoln’s Second Inaugural Address bursts with biblical quotes and allusions. “It sounded more like a sermon than a state paper,” wrote Frederick Douglass, who attended the 1865 speech. One of its lines, from the Gospel of Matthew, also shows up in “The Believer’s Daily Treasure” as the entry for May 13: “Let us judge not that we not be judged.”
Every biography involves acts of judgment, and Lincoln scholars have taken various stances on Lincoln’s faith, from claims that he was a lifelong skeptic who hid his unbelief to the more conventional view that his Christian convictions grew over time. Whatever the truth, there’s a good chance that Lincoln once read what a little devotional book offered for April 14, a simple admonition from John 5:39: “Search the Scriptures.”
