We would certainly expect God's Word to identify itself as such, and each book of the Bible claims, either directly or indirectly, to be the Word of God. The world's most moral book, the Bible, would not proclaim the world's biggest lie. The world's noblest and wisest man, Jesus, would not perpetrate the world's greatest hoax. No one but God could have authored the Bible, for good beings would not falsely claim divine inspiration, and evil beings would not teach such high morality. The Bible is inspired of God, literally 'God-breathed.
Inspiration extends to all parts of the Bible and to every word.
While the human writers chose words that reflected their language, culture, personality, circumstances, and style, God guided the process so that each word would accurately convey His message. As a result, the Bible is infallible, inerrant, and the sole authority for doctrine and Christian living. The Bible is truth. The thirty-nine Old Testament books were recognized as Scripture by the ancient Hebrews, and Jesus and the apostles quoted from or alluded to almost all of them. The accuracy of the Old Testament Hebrew text was safeguarded by the extremely high quality of the scribal transmission process and has received dramatic verification by the recent discovery of the ancient Dead Sea scrolls.
