Why is the Holy Spirit important in the salvation process?

Paul emphasizes in Galatians 3 that the reception of the Holy Spirit is not through the works of the law, but through the hearing of faith. The Holy Spirit plays a crucial role in the salvation process as He is the one who convicts hearts of their need for a Savior and transforms lives. Without the work of the Holy Spirit, no one could come to true faith in Christ, for it is He who opens eyes, regenerates hearts, and creates faith within us. The assurance that we are indwelt by the Holy Spirit serves as a mark of our salvation and rebirth, demonstrating the active work of God in our lives. This transformative power of the Spirit affirms the importance of faith over law in the process of salvation.
