The Lamb, a favorite symbol of Christ, represents the coming sacrifice of Jesus Christ for human redemption. John the Baptist points to the Lamb, often held in his left hand, in many portrayals. There are numerous scriptural references to Christ giving authority to this symbolism depicted in this panel, such as John I:29, “The next day John saw Jesus coming to him, and said, Behold the Lamb of God who takes away the sins of the world.”
John the Baptist holds a scroll with the words “Ecce Agnus Dei” which means “Behold the Lamb of God.” John the Baptist prophesied the coming of the Savior when Jesus came to be baptized by him in Judea. John recognized Jesus and saw the Spirit of God descending like a dove and heard a voice “This is my beloved Son, in whom I am well pleased.” (Matthew 3:13).
