Jesus said to them, "I am the bread of life. He who comes to me will not be hungry, and he who believes in me will never be thirsty.
But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who would betray him. And he said, Therefore I said unto you, that no man can come unto me, except it were given unto him of my Father ( John 6:64-65 ).
