What does the Bible say about the accuracy of God's Word?

The accuracy of God's Word is emphasized throughout scripture, notably in Matthew's account of Christ’s birth. The prophecies made hundreds of years prior, such as Isaiah 7:14 predicting a virgin would bear a son, were fulfilled in Jesus’ birth. The Scriptures assert that God’s Word is settled in the heavens (Psalms 119:89), and nothing can alter its truth. This divine reliability assures believers of both the prophecies regarding Christ's first coming and those concerning His second coming, demonstrating that God's plan unfolds precisely as He ordains.
