Bible: It's holographic in nature and self-referencing. Just like a holographic picture where the parts contain information about the whole light field (electro-magnetic 3 dimensions), the Bible is 4 dimensional: it span's Time and contains information from the whole Time field; hence prophecy. There is enough redundancy coded into the text that doctoring can only achieve so much effect without becoming conspicuous. However, like when breaking a hologram in half how you end up with two lower resolution versions of the original whole, The Bible behaves similarly. The proof is in the individual books (OT & NT authors and individual books). Trinity is everywhere and all over it.
The Holy Book is written by the Holy Spirit across vast time and different authors.
The Holy Spirit has power.
Just to understate it.
