How do we know that the Word of God has power?

In Romans 1:16, Paul states that the gospel is the power of God for salvation to everyone who believes. In John 6:63, Jesus emphasizes that His words are spirit and life, indicating their divine authority and efficacy. Moreover, in 1 Peter 1:23, being born again is associated with the 'incorruptible seed, the Word of God,' highlighting that true life comes from the Scriptures. This life-giving quality of the Word produces faith and renewal, confirming its transformative power in the hearts of believers.
