What does the Bible say about the role of the Holy Spirit in salvation?

According to Scripture, the Holy Spirit plays a crucial role in salvation by illuminating the hearts of individuals to understand the gospel. In 2 Corinthians 4:6, it is stated that God shines in our hearts to give the light of the knowledge of His glory in the face of Jesus Christ. This indicates that the Spirit is not just illuminating from outside but doing an internal work within us, enabling us to perceive the truth of the gospel. The Spirit also convicts the heart of sin and points us to salvation through the sacrificial work of Christ, affirming that without His intervention, we cannot come to faith.

Moreover, the reliance on the Holy Spirit's guidance is evident through Jesus's promise of the Comforter in John 14:26, where the Spirit teaches us all things and reminds us of Christ's words. Therefore, the work of the Holy Spirit is integral not only in conveying the gospel message but also in ensuring reception and understanding, vital for genuine belief and repentance.
