Who wrote the Bible (and how)?
Inspiration is defined (in relation to the Bible) as the fact that God guided human authors to record his Word without error, in the original manuscripts. Proverbs 30:5, 6; Psalm 19; Matthew 5:18; John 10:35; 14:26; Mark 13:31; 2 Timothy 3:16, 17; 2 Peter 1:19-21 and other passages confirm internally the inspiration of Scripture and its preservation throughout the ages. This does not mean that God dictated the information to the authors, but that he guided them using their own personalities, backgrounds, and even research (called dual authorship) — but the one thing that the Holy Spirit would not allow in the human author to express itself was the author’s sinfulness. Thus, the human author participated in every way, except his own sinfulness was kept from influencing or entering the material or words.
Each passage of scripture, then, has a divine Author and a human author.
Some Bible scholars have dubbed this view of biblical authorship verbal, plenary inspiration, meaning that the individual words and ideas/concepts of Scripture were perfectly and completely inspired by God. Matthew 22:23-33; Galatians 3:16; and Psalm 119:89 indicate, again internally, the confidence that Christ and the Bible writers had in the inspiration and preservation of the Bible.
