Because of God’s perfect character and the fact that He cannot lie, it follows that His revelation to us would be without error. Theologian David Dockery offers a good summary of this doctrine, “When all the facts are known, the Bible (in its original writings) properly interpreted in light of which culture and communication means had de- veloped by the time of its composition will be shown to be completely true (and therefore not false) in all that it affirms, to the degree of precision intended by the author, in all matters relating to God and his creation.”
And even though none of the original manuscripts exist today, biblical scholars have sufficiently demonstrated that the Bible has been accurately and reliably preserved for us. Therefore, the Bible you can buy today is essentially the Word of God. Indeed, “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work” (2 Tim. 3:16–17). Passages to explore: Psalm 19:1–4; Matthew 5:18; John 10:35; 17:17; Romans 1:18–25; 2:14–16; 1 Thessalonians 2:13; Titus 1:2; Hebrews 1:1–2; 6:18; 2 Peter 1:16–21.
