I don't doubt Ed Vallowe's love for God or his fervor to serve him, but I think that his focus on numerology is at best misguided and at worst potentially damaging to less discerning Christians. The book's purpose is to "prove" that God wrote the Bible because all the numbers in the Bible somehow line up according to the numerical framework Vallowe describes. The problems with this are twofold:
1) You could never "prove" such a thing. At best, you could provide evidence for or against it. And...
B) It doesn't work.
While you'd get little argument from most scholars that some of the numbers in the Biblical text have symbolic meaning (12 tribes, 12 disciples, 40 days in the desert, 40 days and 40 nights of rain, etc.) but it's hardly obvious that every number up to 40 has some specific meaning, or that compounding them yields a compounded meaning, or that these meanings are consistent throughout scripture.
Furthermore, Vallowe's assertion that not just the numbers in the text, but the chapter and verse numbers themselves have this meaning, is just preposterous. For example, the number 13 is, in many places, symbolic of evil or a bad omen or whatever. Vallowe says it means "Depravity and Rebellion", but the famous "love Chapter" is in I Corinthians 13, and verse 13 of that chapter reads:
"And now these three remain: faith, hope and love. But the greatest of these is love."
Sounds pretty depraved and rebellious, doesn't it? How Vallowe justifies that, not to mention the hundreds of other examples of inconsistencies you could imagine, is beyond me.
Worse yet, he says that his "system" only works in the King James Version of the Bible, not in other translations. Fair enough, but rather than deducing from that fact that perhaps his numerology theory is flawed, or at best, limited to the KJV, he instead concludes that any other translation of the Bible is somehow faulty!
Imagine the gaul you have to have to dismiss hundreds of years worth of Biblical scholarship because his half-baked theory doesn't mesh with their translations! And with all the older texts that have been found in the last 400 years, his insistence upon using an outdated translation based on outdated texts is both ignorant and selfish.
Unfortunately, Christians who don't understand how to actually study the Bible often see this kind of stuff and think they're finding some kind of hidden meanings, while really they're missing out on the real beauty of scripture: The words.
