How the Bible claims inspiration from God
The Old Testament
2 Peter 1:20-21
Knowing this first, that no prophecy of the scripture is of any private interpretation.
For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
The New Testament
1 Peter 1:10-12
Of which salvation the prophets have enquired and searched diligently, who prophesied of the grace that should come unto you:
Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow.
Unto whom it was revealed, that not unto themselves, but unto us they did minister the things, which are now reported unto you by them that have preached the gospel unto you with the Holy Ghost sent down from heaven; which things the angels desire to look into.
Conclusions of plenary-verbal inspiration
It does not teach that all parts of the Bible are equally important but that they are all equally inspired.
It does not guarantee the inspiration of any modern or ancient translation of the Bible, but deals only with the original Greek and Hebrew language.
It does not allow for any false teaching but it does record the lie of someone. The Bible is like a newspaper, most of the time they record everything in reporting the news, regardless of bias. For example, do you think that if David had his choice, the times he screwed up would have never made it? As we read the Bible we must learn to discern between what it records and what God sanctions.
It does not permit any historical, scientific, or prophetical error whatsoever
It does not prohibit personal research
It does not deny the use of extra-biblical sources
It does not overwhelm the personality of the human authors.
It does not exclude the usage of pictorial or symbolic language.
It does not mean uniformity in all details given in describing the same event.
