As if the Bible didn't have enough messages, people have long looked for hidden secrets in it. This isn't about the "Bible codes" (see Who Wrote the Bible Code? : A Physicist Probes the Current Controversy) which has been largely abandoned by most rational people. Gaunt focuses on gematria which is the fact that each Greek and Hebrew letter has a corresponding number. She theorizes that the gematria of key terms and verses in the Bible point to numbers in the design of the universe. Why would God bother with such obscure coding? Good question, but on the other hand He put signs of design in DNA and cells that was only recently detectable (see The Cell's Design: How Chemistry Reveals the Creator's Artistry and Signature in the Cell: DNA and the Evidence for Intelligent Design).
While Gaunt goes through great pains to show links between the Bible's and nature's numbers, it's not always convincing. Take the Earth's diameter she uses in one example. One can find differing figures, and depending on rounding, one can get different results. The ancients often did round numbers for ease, so is Gaunt right or not? Sometimes? Her one number for Jesus she says is the latitude for Bethelham, but a look on a map finds a slightly different one. Did she bother to check? Some have suggested that the continental shift in 2000 years accounts for the change. Possibly. Her calculation of the years between Adam and Noah are suspect because we know counting up generations in the Bible ignores that the Hebrews didn't record everyone (see A Matter of Days: Resolving a Creation Controversy).
She does get into the Golden Section a bit which has long been argued to be a signature of the Creator since it appears so often in nature and man's works (see Divine Proportion: Phi In Art, Nature, and Science and The Golden Section: Nature's Greatest Secret). Math is the universal langauge and don't reoccuring patterns point to design?
She claims Isaiah 19:19,20 and Jeremiah 32:19,20 point to the pyramids in Giza. But why would God use a pagan site for some sort of sign? And then Jeremiah's third location must be Stonehenge. Again, why? She refers to legends about Jeremiah visting Britian. These are very spurious and unable to verify legends.
I will admit that there is some interesting claims here, and perhaps some truth, and this makes a fascinating study. Maybe she clarifies and builds on this in her other books. There are many signs of design in the universe (The Creator and the Cosmos: How the Latest Scientific Discoveries of the Century Reveal God and Intelligent Design: The Bridge Between Science & Theology) that are much easier to see and verify. God is in the numbers, but is he in the Bible's numbers? Decide for yourself.
