John 6:41-44

⁴¹Now the Jews said bitter things about Jesus because of his words, I am the bread which came down from heaven.

⁴²And they said, Is not this Jesus, the son of Joseph, whose father and mother we have seen? How is it then that he now says, I have come down from heaven?

⁴³Jesus made answer and said, Do not say things against me, one to another.

⁴⁴No man is able to come to me if the Father who sent me does not give him the desire to come: and I will take him up from the dead on the last day.
