When therefore the people saw the sign which Jesus did, they said, "This is truly the prophet who comes into the world."

 Jesus' answer was twofold. First, he reminded them that it was not Moses who had given them the manna; it was God. Second, he told them that the manna was not really the bread of God; it was only the symbol of the bread of God. The bread of God was he who came down from heaven and gave men not simply satisfaction from physical hunger, but life. Jesus was claiming that the only real satisfaction was in him.
