Final answer:
John desired the Lamb of God, who represents Christ's sacrificial role, to be revealed universally to all people for the salvation of humanity. This is inferred theologically and historically but is not explicitly addressed in the provided texts.
Step-by-step explanation:
John, represented by the symbol of the eagle in Christian iconography and the writings of the historian Bede, is associated with the anticipation of the Christ's second coming. However, the question regarding whom John wants the Lamb of God to be revealed to is not directly addressed in the provided texts. In a broader theological context, John the Baptist, who is often associated with the revelation of the Lamb of God, declared Jesus as the Lamb of God and desired Him to be revealed to all people, fulfilling the prophecy and providing salvation to humanity. In the context of Christianity and John's portrayal in the Gospels, the Lamb of God symbolizes Christ's sacrifice for the redemption of mankind, an act that is meant to be known and accepted by all believers in order to attain eternal life. This universality is reflected in various scripture passages where the gospel and its truths are to be disseminated to the whole earth as depicted in the various pieces of religious art and the narrative of the evangelists.
