3:16-17 These verses elaborate on 3:15 by explaining Scripture’s effectiveness, its source, and the ways that it gives wisdom to live out our salvation. Paul was speaking of the Hebrew Scriptures (the Old Testament), but his statement can now apply to all Scripture, including the New Testament (see, e.g., 2 Pet 3:15-16). 3:16 The fact that Scripture is inspired by God (literally God-breathed, breathed out by God’s own speech; see also Heb 4:12-13; 2 Pet 1:20-21) does not negate the active involvement of the human authors. But it does affirm that God is fully responsible for his word. Scripture is true, reliable, authoritative, permanent, and powerful because it comes from God himself. Its message is coherent, and it is consistent in its testimony about Jesus Christ (see Luke 24:25-27, 44; John 5:39-40; Acts 3:24; 1 Cor 15:3-4). Thus it has the power to bring salvation and elicit faith. It must not be abused, as the false teachers had been doing (2 Tim 4:2-4; 1 Tim 1:4-7; cp. 2 Pet 3:16), but must be taught properly (2 Tim 2:2, 15). • As a consequence of inspiration, all Scripture is useful. Both the Old Testament and the New Testament are together our guide and teacher in life.
