How do we know the doctrine of the Scriptures is true?

The doctrine of Scripture's truth is affirmed by its ability to illuminate and transform lives. In 2 Corinthians 4, Paul speaks of God shining light into our hearts through knowledge of the glory of God in the face of Christ. This reflects the belief that the Holy Spirit works supernaturally through Scripture, providing insight and understanding that the natural man cannot grasp, thereby affirming its truth. Additionally, believers have experienced the effects of Scripture in their lives, confirming that it yields genuine faith and grace.
