How does God sanctify believers according to scripture?

Sanctification is a vital aspect of the Christian faith, where God sets His people apart for holiness. In Galatians 3:8, it reveals that God not only justifies but also works within believers to produce faith. The role of the Holy Spirit is crucial, as seen in Romans 8:9, which states that those who belong to Christ have the Spirit of God dwelling in them. The Holy Spirit empowers believers to live righteously and brings about a transformation of heart, leading them in sanctification as they continually hear the gospel. Thus, sanctification is both a work of God and a response of faith from the believer.
