How does the Holy Spirit contribute to our salvation?

The Holy Spirit plays a vital role in the process of salvation by effecting regeneration and transformation within the believer. As noted in Titus 3:5, salvation involves 'the washing of regeneration and renewal in the Holy Spirit.' This indicates that the Holy Spirit is actively working to bring about spiritual newness in a believer's life, transforming their desires and enabling them to pursue holiness. Furthermore, in Ephesians 1:13, the Holy Spirit is described as the seal of our inheritance, ensuring our redemption and empowering us to live in accordance with God's will.
