Jesus meant what He said, John 6

JQ said,
Likewise, Ezekiel was commanded to take one third of his hair and beard and burn it in fire, take one third and strike it with the sword, and take the remaining third and let the wind scatter it. The interpretation of this symbolic act was to be presented as "This is Jerusalem". (Ezekiel 5:1ff)

Ezekiel is not God, is he? Jesus is God, isn't He?

If Jesus were speaking symbolically, He would have called these guys back and said, "Hey, guys, come on, I was speaking symbolically." 

John 6:60-66

King James Version (KJV)
60 Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?
61 When Jesus knew in himself that his disciples murmured at it, he said unto them, Doth this offend you?
62 What and if ye shall see the Son of man ascend up where he was before?
63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
66 From that time many of his disciples went back, and walked no more with him.


But He didn't. And He didn't take the Apostles aside and say to them, "This is a symbol." No, He didn't. He said:

67 Then said Jesus unto the twelve, Will ye also go away?

He said exactly what He meant.
