Legitimate question!
1. Historical accuracy: The Bible gives historical reference points, and archeology eventually backs it up with extra Biblical sources, e.g. King David, Sodom & Gomorrah, the Hittites, etc.
2. Manuscript evidence: The Bible is proven consistent historically, with ancient manuscripts agreeing with current ones >95% of the time, and we have numerous examples, e.g. The Dead Sea Scrolls.
3. Internal consistency
4. Agreement with PROVABLE science. The science (so called) of origins of the universe, life and man, are conjecture, and do a poor job fitting existing evidence. e.g the hydrological cycle, the circle of the Earth, the reasonableness of the dimensions of the ark, etc.
5. Human Nature: the Bible illustrates man, heroes and villains alike, in their sinful depravity (why did not the scribes omit David's adultery, or Ham's perversion, or Jacob's deceit?) And it still explains human nature.
6. Unchanging: Unlike the modern science of Origins, the Bible has asserted the same thing for 3.5 Millennnia. The "Big Bang" conjecture will eventually be discarded for some newer.
7. Fulfilled Prophecy: just on the birth, life and death of the Messiah in overwhelmingly convincing.
So, why do I believe it is EXACTLY what God told Moses?
A. The Bible attests that Jesus was born of a virgin, was sinless, was crucified, dead and buried, and rose on the 3rd day, according to the scriptures. The disciples all were martyred confessing this to be true (John survived only to be exiled), and they were in a position to verify these facts!
B. As such, I believe Jesus was the Son of God, and what he said and preached was reliably recorded in the Gospels. Manuscript evidence is overwhelming here, with >25,000 examples extant, more than ANY other historical document before 1600.
C. Jesus said
Matthew 5:18 "For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished."
The first 5 books of the Bible are known as the Pentateuch, or, Books of the Law. Jesus is here confirming the validity and accuracy of these books, which contains the aforementioned quotes regarding creation.
So, I ask you, why would you assert it is not a precise communication from God?
So there’s no actual evidence that God sat down at his desk and wrote the Bible, or recorded it in any way such as we do today like putting it in a memory chip, hard disk, or printing a hard copy?
Doesn’t the evidence show that it is actually a written recollection (by humans) of oral tradition?
