The Holy Bible is the Word of God.
This means that the men who penned the words of the scriptures were holy men of God inspired and controlled by God in what they wrote. God supernaturally preserved their writings over the ages and allowed them to be assembled into what we now know to be the bible.
The Word of God is not just a book with pages and ink.
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life." -John 6:63
"1In the beginning was the Word, and the Word was with God, and the Word was God" -John 1:1
"14And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth." -John 1:14
The Bible is true.
