John 6:37-44

All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out. For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.” Therefore the Jews were grumbling about Him, because He said, “I am the bread that came down out of heaven.” They were saying, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does He now say, ‘I have come down out of heaven’?” Jesus answered and said to them, “Do not grumble among yourselves. No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day.
