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 perfect, throughly furnished unto all good works (II Timothy 3:16,17).
This passage is the most definitive of all passages on the inspiration of the Bible. It explicitly repudiates all the false concepts which men have developed to try to escape this vital doctrine.
For example, it repudiates the humanistic theory of inspiration, which says that the writers were inspired with the same quality of exalted feelings that inspired other great writers. But this verse attributes it not to human inspiration, but to the inspiration of God.
Then, there is the partial theory of inspiration, which says that part of the Bible is inspired (the religious parts), but that part of it is not (the scientific and historical parts). But our verse says that all Scripture is inspired! The dynamic theory says the thoughts are inspired, but not the words. However, it is the Scriptures that are inspired, not the thoughts of the men who wrote them. The Scriptures mean the writingsthe actual words written.
The encounter theory says the Scriptures are not inspired in themselves, but only become inspired when a reader encounters God through reading them. This, also, is false. The Scriptures are inspired regardless of how they affect the reader. Actually, the phrase given by inspiration of God is one word in the Greek, meaning God-breathed.
Thus, plenary verbal inspiration and complete divine origin and authority of all the Holy Scriptures is the true Biblical doctrine. When one does accept the God-breathed authority of Scripture, however, he has an infinite resource, serving as an inerrant framework for all true wisdom and knowledge, and leading him into full maturity in the Christian life.
