Jesus answered, "What God wants you to do is to believe in the one he sent."
They replied, "What miracle will you perform so that we may see it and believe you? What will you do?
Our ancestors ate manna in the desert, just as the scripture says, "He gave them bread from heaven to eat.' " 1
"I am telling you the truth," Jesus said. "What Moses gave you was not the bread from heaven; it is my Father who gives you the real bread from heaven.
For the bread that God gives is he who comes down from heaven and gives life to the world."
"Sir," they asked him, "give us this bread always."
"I am the bread of life," Jesus told them. "Those who come to me will never be hungry; those who believe in me will never be thirsty.
Now, I told you that you have seen me but will not believe.
Everyone whom my Father gives me will come to me. I will never turn away anyone who comes to me,
because I have come down from heaven to do not my own will but the will of him who sent me.
And it is the will of him who sent me that I should not lose any of all those he has given me, but that I should raise them all to life on the last day.
