What does the Bible say about the authority of God's word?

The authority of God's word is clearly articulated in Scripture, emphasizing its infallibility and inerrancy. Isaiah underlines that the words spoken through him are God's own, and thus carry divine authority. This is vital for believers, as it establishes the foundation for faith and obedience. Paul reminds us in 2 Timothy 3:16-17 that 'all Scripture is breathed out by God' and is profitable for teaching, reproof, correction, and training in righteousness. This supports the assertion that God's word is not merely a collection of human thoughts but the very communication from the Sovereign Maker, calling all to respond.
