How does the Holy Spirit determine a believer’s eternal destiny?

The eternal destiny of a believer is intricately linked to the work of the Holy Spirit in their life. According to Romans 8, the assurance of salvation and eternal life is provided through the indwelling presence of the Holy Spirit. When a person places their faith in Jesus, they are sealed with the Holy Spirit, making them a child of God. This sealing acts as a guarantee of their inheritance and future resurrection. Therefore, the presence of the Spirit is not only a mark of identity but also the determining factor regarding their eternal state before God.
