One of the stone panels here threads together the fall of humanity (represented by the sin of Adam and Eve), which shows our need for a Savior, with the destructive but cleansing flood of Noah's time, which foreshadowed the Sacrament of Baptism, and Abraham's willingness to obey God by sacrificing his son Isaac, which foreshadowed the death of the Son of God for our salvation. The text from Hebrews 9:22 pulls the threads together in Christ.
