John 6:29-39 NIRV

29 Jesus answered, "God's work is to believe in the One he has sent."
30 So they asked him, "What miraculous sign will you give us? What will you do so we can see it and believe you?
31 Long ago our people ate the manna in the desert. It is written in Scripture, 'The Lord gave them bread from heaven to eat.' "(Exodus 16:4; Nehemiah 9:15; Psalm 78:24,25)
32 Jesus said to them, "What I'm about to tell you is true. It is not Moses who has given you the bread from heaven. It is my Father who gives you the true bread from heaven.
33 The bread of God is the One who comes down from heaven. He gives life to the world."
34 "Sir," they said, "give us this bread from now on."
35 Then Jesus said, "I am the bread of life. No one who comes to me will ever go hungry. And no one who believes in me will ever be thirsty.
36 "But it is just as I told you. You have seen me, and you still do not believe.
37 Everyone the Father gives me will come to me. I will never send away anyone who comes to me.
38 "I have not come down from heaven to do what I want to do. I have come to do what the One who sent me wants me to do.
39 The One who sent me doesn't want me to lose anyone he has given me. He wants me to raise them up on the last day.
