How do we know that Scripture is the voice of God?

Scripture is regarded as the voice of God because it serves as the primary means through which He communicates with humanity after the Ascension of Christ. John 10:27 states, 'My sheep hear My voice,' indicating that His true followers understand and recognize His message through His Word. The Bible, as the written expression of God’s thoughts, carries authority and life. It is more than just historical narratives or moral teachings; it is God's revelation to us, which transforms and sustains those who engage with it by faith. This is why Scripture is considered 'living and active' (Hebrews 4:12), capable of penetrating our hearts and leading us to the truth of who God is through Christ.
