A lot of us don’t understand the inerrancy of the Bible. Inerrancy means no mistakes. This would be possible only if the Bible is a supernatural library of books.
Inerrancy applies to the original text given to the original authors of Scripture. Inerrancy does not apply to the human authors, but only to the specific words of the text. When John, Paul, James, and Peter weren’t writing divinely inspired Scripture, the were ordinary imperfect men. That is what makes the Bible miraculous.
Inerrancy does not exempt a copyist from making a mistake when writing a new manuscript from an old manuscript. Remember, before the printing press, copies were made by hand. The more copies of these hand-written New Testament manuscripts that we find, the more likely we are to find these variations. There are an enormous amount of variations in copied texts because we have an enormous amount of existing manuscripts. In 2016, there were 5,856 Greek manuscripts of New Testament books with an average of 450 pages. (By comparison, the average classical Greek author has less than 15 copies of his work in existence today.) The scholars that compare these 5,856 manuscripts can determine that the New Testament is 99.99% accurate to the originals, and the remaining potential inaccuracies do not affect any important Christian doctrine.
Inerrancy does not extend to translations of the Bible into various languages… including the Authorized King James Version.
Inerrancy does not extend to preachers, evangelists, or modern-day super-apostles. When someone says, “Thus saith the Lord,” it means, listen up and measure each and every word that is spoken against the infallible inspired written Word of God… even if they make up fancy words like revelation-knowledge or other bunk to manipulate you.
Inerrancy does not extend to genuine prophetic utterances, messages in tongues, private or public glossolalia, interpretation of tongues, or other gifts of the Spirit. All these must be subjected to scrutiny by the Scriptures.
If God supernaturally inspired the Bible, it contains no errors. If God supernaturally inspired the Bible, it is an authoritative word over our lives. If the Bible originally contained mistakes, it isn’t likely that it came from God, and therefore would not have much authority.
The Bible is a supernatural book in that it is a God-breathed, collection of genuine prophetic writings, carrying divine authority as the Word of God.
All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work. (2 Timothy 3:16,17)
(Did you know that when Paul wrote 2 Timothy 3:16,17, the New Testament was still in the process of being written by himself and the other authors. He wrote this about the Hebrew Scriptures that later came to be called the Old Testament by Christians?)
