Jesus answered, “The work of God is this: to believe in the one he has sent.”
So they asked him, “What sign then will you give that we may see it and believe you? What will you do?
Our ancestors ate the manna in the wilderness; as it is written: ‘He gave them bread from heaven to eat.’ ”
Jesus said to them, “Very truly I tell you, 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.
For the bread of God is the bread that comes down from heaven and gives life to the world.”
“Sir,” they said, “always give us this bread.”
Then Jesus declared, “I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.
But as I told you, you have seen me and still you do not believe.
All those the Father gives me will come to me, and whoever comes to me I will never drive away.
For I have come down from heaven not to do my will but to do the will of him who sent me.
And this is the will of him who sent me, that I shall lose none of all those he has given me, but raise them up at the last day.
