A lot vs. Alot: 9 Grammatical Pitfalls
c.1300, "immediate influence of God or a god," especially that under which the holy books were written, from Old French inspiracion "inhaling, breathing in; inspiration," from Late Latin inspirationem (nominative inspiratio), noun of action from past participle stem of Latin inspirare "inspire, inflame, blow into," from in- "in" (see in- (2)) + spirare "to breathe" (see spirit). Literal sense "act of inhaling" attested in English from 1560s. Meaning "one who inspires others" is attested by 1867.
inspiration in·spi·ra·tion (ĭn'spə-rā'shən)
The inhalation of air into the lungs.
that extraordinary or supernatural divine influence vouchsafed to those who wrote the Holy Scriptures, rendering their writings infallible. "All scripture is given by inspiration of God" (R.V., "Every scripture inspired of God"), 2 Tim. 3:16. This is true of all the "sacred writings," not in the sense of their being works of genius or of supernatural insight, but as "theopneustic," i.e., "breathed into by God" in such a sense that the writers were supernaturally guided to express exactly what God intended them to express as a revelation of his mind and will. The testimony of the sacred writers themselves abundantly demonstrates this truth; and if they are infallible as teachers of doctrine, then the doctrine of plenary inspiration must be accepted. There are no errors in the Bible as it came from God, none have been proved to exist. Difficulties and phenomena we cannot explain are not errors. All these books of the Old and New Testaments are inspired. We do not say that they contain, but that they are, the Word of God. The gift of inspiration rendered the writers the organs of God, for the infallible communication of his mind and will, in the very manner and words in which it was originally given. As to the nature of inspiration we have no information. This only we know, it rendered the writers infallible. They were all equally inspired, and are all equally infallible. The inspiration of the sacred writers did not change their characters. They retained all their individual peculiarities as thinkers or writers. (See BIBLE ØT0000580; WORD OF GOD.)
