About the Cover: Everything about the Weimar altarpiece centers on Jesus: angels announcing the Savior to shepherds, the bronze serpent lifted uplifted in the wilderness, and John the Baptist pointing to the Lamb and the cross. As Moses holds up the law to a man chased by death and the devil toward hell, the man looks up to Christ for mercy. Trusting in the Word, which Luther holds in his hands, we, like Cranach the Elder standing next to Luther, are purified by the blood of Christ.
