Jesus answered them, "This is the work of God, that you believe in him whom he has sent."
They said therefore to him, "What then do you do for a sign, that we may see, and believe you? What work do you do?
Our fathers ate the manna in the wilderness. As it is written, 'He gave them bread out of heaven to eat.'"
Jesus therefore said to them, "Most assuredly, I tell you, it wasn't Moses who gave you the bread out of heaven, but my Father gives you the true bread out of heaven.
For the bread of God is that which comes down out of heaven, and gives life to the world."
They said therefore to him, "Lord, always give us this bread."
Jesus said to them. "I am the bread of life. He who comes to me will not be hungry, and he who believes in me will never be thirsty.
But I told you that you have seen me, and yet don't believe.
All those who the Father gives me will come to me. Him who comes to me I will in no way throw out.
For I have come down from heaven, not to do my own will, but the will of him who sent me.
This is the will of my Father who sent me, that of all he has given to me I should lose nothing, but should raise them up at the last day.
