John 6:52 The Jews therefore quarrelled among themselves, saying, “How can this Man give us His flesh to eat?”
When we take the word of Jesus literally we miss the point all together!
Jesus did not come as a scientific text book to give us the exact answers of life, the universe and everything; we should not expect to gain that from our Bibles.
What Jesus did give us is hope through promises of what is to come in our futures. If we want to live with Him we have to study His words and gain insight into what they mean, not take them all literally!
Jesus gave His body so we could have life afterward; no matter which way we look at it, it is an enormous promise to get into our heads!
