The title of the painting on the cover is Justice Lifts the Nations.
It was painted by Paul Robert in 1905. Francis A. Schaeffer explains the meaning
of this painting in his book, How Should We Then Live?:
"It is on the stairway in the old Supreme Court Building in Lausanne
where the judges had to pass each time before going up to try a case. Robert
wanted to remind them that the place which the Reformation gave to the Bible
provided a basis not only for morals but for law. Robert pictured many types of
legal cases in the foreground and the judges in their black robes standing
behind the judges' bench. The problem is neatly posed: How shall the judges
judge? On what basis shall they proceed so that their judgment will not be
arbitrary? Above them Robert painted Justice standing unblindfolded, with her
sword pointed not vertically upward but downward toward a book, and on the book
is written The Law of God." (p. 106).
