John 6:37-44

37All that the Father gives me will come to me, and whoever comes to me I will never cast out.

38For I have come down from heaven, not to do my own will but the will of him who sent me.

39And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.

40For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day."

41So the Jews grumbled about him, because he said, "I am the bread that came down from heaven."

42They said, "Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, 'I have come down from heaven'?"

43Jesus answered them, "Do not grumble among yourselves.

44No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day.
