How does Jesus demonstrate His role as Savior of the world?

Jesus is designated as the Savior of the world in that He provides spiritual nourishment and life to those who believe in Him (John 6:33, 51). His atoning sacrifice on the cross explicitly takes away the sin of 'the world'—which refers to His chosen people, as articulated by John the Baptist (John 1:29). His redemptive work is comprehensive for all of God’s elect, showing that through His sacrifice and bread of life, believers are given eternal life. This underscores the need for faith in Him to partake in the life He offers.
