John 6:37-45

All those the Father gives me will come to me, and whoever comes to me I will never drive away. For I have come down from heaven not to do my will but to do the will of him who sent me. And this is the will of him who sent me, that I shall lose none of all those he has given me, but raise them up at the last day. For my Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise them up at the last day.”
At this the Jews there began to grumble about him because he said, “I am the bread that came down from heaven.” They said, “Is this not Jesus, the son of Joseph, whose father and mother we know? How can he now say, ‘I came down from heaven’?”
“Stop grumbling among yourselves,” Jesus answered. “No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day. It is written in the Prophets: ‘They will all be taught by God.’ Everyone who has heard the Father and learned from him comes to me.
