Just seems that G-d would talk to us through scripture rather than hide stuff in sequences. Unless (twilight Zone music here) there is intelligence that can understand these codes by just looking at them. Smarter than me, that's for sure.
I have as well and have found some truly astonishing things. Here's the rub, for me: these things speak of a history that may yet be but tend to be a distraction from the far clearer "what is". Even the correlations found are open to endless debate. So, Noah's flood correlates with the Black Death. OK, now what?
As an amusing aside, if you render the digital representation of the number 666 (convert the number to its corresponding digital form) You get an anti-pallindrome, exactly opposite forwards to back. If you do the same with the Jewish terms for God, they are pallindromes (exactly the same forwards or back). Significant? I used to think so, now I think probably not.
