If the Bible was "God breathed" (or inspired or whatever is claimed) and if God is taken to be all-wise, why wouldn't "he" have chosen better writers – people with ability to convey information clearly without ambiguities, contradictions, errors, and need for "interpretation"?
Compared to some of the world's great writers, Bible writers "come in third in a two-horse race." There may be some kernels of wisdom (or "diamonds among the dung" as Thomas Paine said). However, the vast bulk of the 800,000 words or so of the bible are intelligible, inapplicable, incredible, fluff that convey no wisdom or guidance to modern people.
Here is a list of the top twenty best writers of all time (from a list of the top one hundred).
A supposedly omniscient God would have (by definition) known that the Bible would be variously transcribed, translated, edited, revised, altered, etc since it is so poorly written -- and choose (or "inspire") some of the likes of the above to produce a better product.William Shakespeare
