27 Do 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. 28 Then they asked him, "What must we do to do the works God requires?" 29 Jesus answered, "The work of God is this to believe in the one he has sent." 30 So they asked him, "What miraculous sign then will you give that we may see it and believe you?" What will you do? 31 Our forefathers ate the manna in the desert; as it is written: 'He gave them bread from heaven to eat.' 32 Jesus 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 heave. 33 For the bread of God is he who comes down from heaven and give life to the world." 34 "Sir," they said, "from now on give us this bread." 35 Then 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 go thirsty.
