Good post.
The Codes are VALID given some IF's
And depending on one's definition of valid.
I personally believe that SOME of the codes which do NOT pass statistical length muster will turn out to have been valid. But one can't say so statistically ahead of time.
The codes which are relatively astronomically long--60+ letters etc. are statistically off the wall--especially when in complex clusters with key word congruence between the code and codes clustering around it AND the surface text.
But I do think God is somewhat having fun with the code given their cryptic-ness. It's another set of puzzles for us to solve. And, I think those who walk in Love with God will likely benefit more from the codes than those who live in denial about God in general.
I think your correlations etc. are interesting and likely to be valid.
I'm rather skeptical about the whole Bible Code idea, although I admit I haven't studied it extensively. It seems to me that folks get ideas and try to read these ideas into the Bible. The problem is that you can make almost anything "fit" if you try hard enough. It's like that numerology craze, where people are always predicting the date of the Second Coming or other events. They always figure that the earth is 4,000 years old, they add other dates to their "formula," and from that they "predict" when the Second Coming will occur. They start out with a false premise (that the earth is only 4,000 years old and that God has a fetish for the number 7), and read in other things that may not even be relevant. One could "prove" anything that way.
I think it appeals to people's pride to believe that God has some secret code or that the Bible has a hidden meaning, and -- praise the Lord -- one just happens to be smart enough to read God's mind and figure out all the "secret" messages! It kind of reminds me of the Gnostics, who had umpteen "Secret Gospels" from which they got all kinds of esoteric doctrines.
The plain words in the Bible can be hard enough to understand without reading in to them all sorts of marginal issues. I think people should be very careful when it comes to speculation.
