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

The supremacy of God's Word is emphasized throughout Scripture, especially in passages like Jeremiah 23, where God warns against false prophets who speak from their own hearts rather than His Word. Jeremiah declares that God's Word is eternal, unlike the transient nature of human words. It is the source of truth and authority, which believers can rest their souls upon, for it ultimately points to Jesus Christ, the embodiment of God's message of salvation. The assurance that ‘faith cometh by hearing, and hearing by the Word of God’ highlights the indispensable role of God's Word in our faith journey, reinforcing its supremacy.
