How does God's Word give light and understanding?

The light and understanding that come from God's Word are specifically attributed to the work of the Holy Spirit in the hearts of believers. As the Scripture enters into the soul, it dispels darkness and brings about spiritual insight, allowing individuals to see and comprehend God's truth. This process aligns with the promise in 2 Corinthians 4:6, where God commands light to shine out of darkness and reveals the knowledge of His glory. Therefore, the continual reading and meditation on God's Word lead to greater illumination and understanding as the Holy Spirit works within the believer, transforming their understanding and behavior in alignment with Christ.
