Jesus therefore lifting up his eyes, and seeing that a great multitude was coming to him, said to Philip, "Where are we to buy bread, that these may eat?"

 Jesus was well aware that some would not only reject his offer but would reject it with hostility. No man can accept him unless he is moved by the Spirit of God to do so but to the end of the day a man can resist that Spirit. Such a man is shut out not by God, but by himself.
