26Jesus answered, "I tell you the truth, you are looking for me, not because you saw miraculous signs but because you ate the loaves and had your fill.
27Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you. On him God the Father has placed his seal of approval."
28Then they asked him, "What must we do to do the works God requires?"
29Jesus answered, "The work of God is this: to believe in the one he has sent."
30So they asked him, "What miraculous sign then will you give that we may see it and believe you? What will you do?
31Our forefathers ate the manna in the desert; as it is written: 'He gave them bread from heaven to eat.' "
32Jesus said to them, "I tell you the truth, it is not Moses who has given you the bread from heaven, but it is my Father who gives you the true bread from heaven.
33For the bread of God is he who comes down from heaven and gives life to the world."
34"Sir," they said, "from now on give us this bread."
35Then Jesus declared, "I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty.
36But as I told you, you have seen me and still you do not believe.
