How does the Holy Spirit work in our hearts during redemption?

According to Scripture, the Holy Spirit plays an essential role in redemption by convicting sinners of their need for salvation. As mentioned in Isaiah 59, when the Holy Spirit comes, He imparts understanding, leads individuals to repentance, and reveals Christ as their only hope. John 16:8 explicitly states that the Spirit convicts the world concerning sin, righteousness, and judgment. This divine action enables the believer to recognize their sinful state, prompting them to turn toward Christ in faith, thereby completing the work of salvation as outlined in Ephesians 2:1-10.
