How does the promise of the Spirit relate to salvation?

As highlighted in Galatians 3:14, the promise of the Spirit is given to believers through faith, emphasizing that the work of the Holy Spirit is integral to salvation. The Spirit empowers us to believe the gospel and transforms our hearts, enabling us to live out our faith in Christ. This promise assures us that our relationship with God is not built on our efforts but on His finished work and the gifting of the Holy Spirit, affirming that our salvation and sanctification are entirely by grace.
