3:16 All scripture. “All Scripture”—that is, every individual “scripture”—is included in this reference, not just the thoughts, but the actual writings, the words written down. Thus the words, not just the “thoughts,” are inspired of God. This one verse repudiates the idea of “partial inspiration” and also that of so-called “dynamic inspiration.” The true doctrine is plenary verbal inspiration of the Holy Scriptures. Since God is omniscient, the Scriptures are, therefore, infallible and free from error of any kind.
3:16 inspiration of God. “Given by inspiration of God” is all one word in the Greek, theopneustos, meaning “God-breathed.” This word refutes any idea of human inspiration (such as a poet, or musician might claim). The Scriptures, by whatever particular methods God may have used in their various parts, including the individual human abilities and researches of the various human writers (whose abilities He had created and whose researches He had guided), as they finally came from their Spirit-guided minds and pens, are in effect God-breathed.
3:16 doctrine. “Doctrine” is the same as “teachings.” All that the Bible teaches is true and profitable for study.
3:16 reproof. “Reproof” means “conviction” or “evidence” (as the word is translated in Hebrews 11:1). The Scriptures themselves give abundant internal evidence of their own divine inspiration.
3:16 correction. “Correction” means “setting right.” This is the only occurrence of this particular word (Greek epanorthosis) in the New Testament.
