How do we know that God has preserved His Word?

In Psalm 12, the assurance is given that God will preserve His words from this generation forever. This promise is rooted in God’s sovereignty, meaning that if He can create the universe from nothing, He is fully capable of ensuring that His Word remains intact and unaltered through the ages. The consistency and authority of the Bible throughout history affirm its preservation. Furthermore, the fact that the Scriptures consistently point to the atonement of Jesus Christ reinforces their divine origin and reliability.
