"What sign then are You going to do so we may see and believe You?" they asked. "What are You going to perform?
Our fathers ate the manna in the wilderness, just as it is written: He gave them bread from heaven to eat. "
Jesus said to them, "I assure you: Moses didn't give you the bread from heaven, but My Father gives you the real bread from heaven.
For the bread of God is the One who comes down from heaven and gives life to the world."
Then they said, "Sir, give us this bread always!"
"I am the bread of life," Jesus told them. "No one who comes to Me will ever be hungry, and no one who believes in Me will ever be thirsty again.
But as I told you, you've seen Me, and yet you do not believe.
Everyone the Father gives Me will come to Me, and the one who comes to Me I will never cast out.
For I have come down from heaven, not to do My will, but the will of Him who sent Me.
This is the will of Him who sent Me: that I should lose none of those He has given Me but should raise them up on the last day.
For this is the will of My Father: that everyone who sees the Son and believes in Him may have eternal life, and I will raise him up on the last day."
