What Does 2 Timothy 3:16 Mean?

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. This is one of Scripture's most crucial verses on its own nature. "All scripture" (pasa graphē, πᾶσα γραφή). Pasa (πᾶσα) means all, every—no exceptions. Graphē (γραφή) means writing, Scripture—technical term for sacred writings. Paul refers minimally to the Old Testament, but the principle extends to New Testament writings (2 Peter 3:15-16 calls Paul's letters "Scripture"). All Scripture, every part, carries equal divine authority.

"Is given by inspiration of God" (theopneustos, θεόπνευστος). This compound combines theos (θεός, "God") and pneō (πνέω, "breathe")—literally "God-breathed." Scripture isn't human writing about God but God's own breath, His spoken word written down. Theopneustos describes Scripture's origin and nature: God exhaled it. This is verbal plenary inspiration—God superintended the writing of every word, using human authors' personalities and vocabularies while ensuring His intended message was inerrantly recorded. Scripture is simultaneously human and divine: human authors wrote, yet God breathed every word.

Because Scripture is God-breathed, it's "profitable" (ōphelimos, ὠφέλιμος)—useful, beneficial, advantageous. Four functions follow: (1) "For doctrine" (pros didaskalian, πρὸς διδασκαλίαν)—teaching truth, establishing beliefs. (2) "For reproof" (pros elegmon, πρὸς ἐλεγμόν)—exposing error, convicting of sin. (3) "For correction" (pros epanorthōsin, πρὸς ἐπανόρθωσιν)—restoring to right path, fixing what's wrong. (4) "For instruction in righteousness" (pros paideian tēn en dikaiosynē, πρὸς παιδείαν τὴν ἐν δικαιοσύνῃ)—training in righteous living, disciplined godliness. Scripture provides comprehensive guidance for belief and behavior.
