John 6:29-39 NCV

29 Jesus answered, "The work God wants you to do is this: Believe the One he sent."
30 So the people asked, "What miracle will you do? If we see a miracle, we will believe you. What will you do?
31 Our fathers ate the manna in the desert. This is written in the Scriptures: 'He gave them bread from heaven to eat.'"
32 Jesus said, "I tell you the truth, it was not Moses who gave you bread from heaven; it is my Father who is giving you the true bread from heaven.
33 God's bread is the One who comes down from heaven and gives life to the world."
34 The people said, "Sir, give us this bread always."
35 Then Jesus said, "I am the bread that gives life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty.
36 But as I told you before, you have seen me and still don't believe.
37 The Father gives me my people. Every one of them will come to me, and I will always accept them.
38 I came down from heaven to do what God wants me to do, not what I want to do.
39 Here is what the One who sent me wants me to do: I must not lose even one whom God gave me, but I must raise them all on the last day.
