The Bible claims it comes from God:
First, you must understand this. No prophecy in the Scriptures ever came from the prophet’s own mind. Prophecy never comes from what a person thinks. Instead, the Holy Spirit gave the prophets the words of God’s message. (2 Peter 1:20 – 21)
Jesus says the Bible is as important as
food:
But Jesus answered the Devil, saying, ‘People wrote this down in the book of God. Man does not live only on bread. Man needs every word from God so that he can really live. (Matthew 4:4)
