I believe every word Jesus said. I believe him when he said "I am the door." you know ... wood... hinges. I believe him when he said "i am the path"... you know... pavement... or bricks. Come on people. Learn to recognize metaphors, similes, figures of speech.
I'm sure you're very familiar with Scripture -- familiar enough to realize that when Christ was speaking figuratively He made that very clear. When the disciples or Pharisees asked Him for an explanation of a parable (like the door of the sheepfold, or the sower who went forth to sow), He gave it to them, and explained to them what He meant. John even adds that they didn't understand what he was saying until he explained further.
But in John 6, when His disciples said, "This is a hard saying -- who can hear it?" He didn't say, "No, you misunderstood. Here is the explanation." Instead, He reiterated three times that His flesh is food indeed, and His blood is drink indeed, and that if you do not eat His flesh and drink His blood, "there is no life in you." And to believing Jews that was a horrific, fundamental heresy that they could not accept.
And when many of His disciples walked away and followed Him no more because they could not accept His teaching, He did not correct them. He let them go. Why would God let His followers walk away because of a mere misunderstanding of a figure of speech?
