How do we know the doctrine of Scripture's inspiration is true?

The doctrine of plenary inspiration asserts that all Scripture is God-breathed, as indicated in 2 Timothy 3:16. This means every word of Scripture is pure and carries divine authority. The apostle Peter also affirms that holy men of God spoke as they were moved by the Holy Spirit (2 Peter 1:21). The accuracy of the original texts and the enduring truths of Scripture throughout the ages further affirm its divine inspiration. When believers experience the illumination of God's Word in their lives, they witness its truth and power personally.
