You assume a lot. I have posted the relevant part of John 6.
Check out my previous posts.
You have many quotes, some have relevance, and others do not.
Many can not accept the literal words of Jesus.Yes the Bible is full of different literary styles.
Many have responded with personal opinion, but do not refute the clear logical words of Jesus.
The words were important to Jesus, and I believe that many are rejecting His words and rejecting Him.
By your question: “Now, what is the real revelation found in John 6, eating food, or believing in the Living Word?” I believe that you do not understand the The Word or the Truth. It is not about eating food, but accepting God and believing His word.
Many claim to be followers of Christ, but do not believe or accept some of His teachings (even if they say so). Christ knows who believes in Him.
John 1:11-14 (KJV) - 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. 14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
And another one to ponder. Better take this one literally too.
Matthew 15:5-17 (KJV) - 5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; 6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. 7 Ye hypocrites, well did Esaias prophesy of you, saying, 8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. 9 But in vain they do worship me, teaching for doctrines the commandments of men. 10 And he called the multitude, and said unto them, Hear, and understand: 11 Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man. 12 Then came his disciples, and said unto him, Knowest thou that the Pharisees were offended, after they heard this saying? 13 But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up. 14 Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch. 15 Then answered Peter and said unto him, Declare unto us this parable. 16 And Jesus said, Are ye also yet without understanding? 17 Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?
Golly!
I just did the same!!!
