"It is the Spirit who gives life...The WORDS that I speak to you are spirit, and THEY are life. But there are some of you who do not believe. Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father." John 6:63-65
Yes, the Words he brings are Spirit and life. But you cannot, you *cannot* my friend, interpret this passage as negating what was said earlier. "Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you." Either you accept BOTH statements as literally true, or you are playing fast and loose with the Bible. You seem to want this passage above to cancel out the earlier one.
You don't believe Christ is in the habit of contradicting Himself do you?
