How do we know that the Bible is the true Word of God?

We know the Bible is the true Word of God because it comes not from human will but from divine inspiration. As stated in 2 Peter 1:20-21, prophecy in Scripture is not a matter of private interpretation; rather, it was spoken by holy men of God who were moved by the Holy Spirit. This divine origin explains the remarkable unity and consistency of the Bible across different authors and centuries, leading us to recognize it as a coherent message that centers around Jesus Christ. It is not mere literature but the very voice of God as revealed to His people.
