Jesus answered and said to them, "This is the work of God: that you believe in [the one] whom that one sent."
So they said to him, "Then what sign will you perform, so that we can see [it] and believe you? What will you do?
Our fathers ate the manna in the wilderness, just as it is written, 'He gave them bread from heaven to eat.'
Then Jesus said to them, "Truly, truly I say to you, Moses did not give you bread from heaven, but my Father is giving you the true bread from heaven!
For the bread of God is the one who comes down from heaven and gives life to the world."
So they said to him, "Sir, always give us this bread!"
Jesus said to them, "I am the bread of life. The one who comes to me will never be hungry, and the one who believes in me will never be thirsty again.
But I said to you that you have seen me and do not believe.
Everyone whom the Father gives to me will come to me, and the one who comes to me I will never throw out,
because I have come down from heaven not that I should do my will, but the will of the one who sent me.
Now this is the will of the one who sent me: that everyone whom he has given me, I would not lose [any] of them, but raise them up on the last day.
