Inspiration simply means “God-breathed.”
Even though God used men with their distinctive personalities & writing styles, God divinely inspired the very words they wrote… “carried along by Holy Spirit”.
Inspiration means the Bible is truly the Word of God and makes the Bible unique among all other books. 1 Cor 2:12-13 • 2 Tim 3:16-17 • 2 Peter 1:21
The doctrine of inspiration only applies to the original writings (autographs).
The doctrine of preservation deals with the survival and accuracy of the copies (manuscripts).
