In what manner does sanctification occur in a believer's life?

Sanctification in a believer's life occurs primarily by God's free grace and renewal. This process is fundamentally rooted in the divine work of the Holy Spirit, who transforms believers from the inside out, enabling them to grow in holiness and Christlikeness. It emphasizes that sanctification is not merely a result of human effort or adherence to rules, but rather a spiritual work instigated and sustained by God.

This grace-driven renewal reflects the New Testament teaching that believers are transformed through their relationship with Christ, empowering them to pursue a life that aligns with God's desires. The emphasis on God's grace highlights that sanctification is a journey of growth and change, contingent upon God's mercy rather than individual performance.

While strict adherence to laws, personal discipline, and communal worship can play roles in a believer's spiritual development, they do not constitute the foundation of sanctification. Instead, they can be viewed as means or contexts through which God's grace operates, rather than the source or the primary mechanism of the sanctifying process itself.
