How does grace relate to mortification of sin?

Grace plays a fundamental role in the mortification of sin for believers, as it is by grace that we are not only saved but also enabled to live righteously. In Romans 8:13, Paul indicates that we can mortify the deeds of the body through the Spirit. This points to the necessity of grace in our fight against sin; we must acknowledge that our strength comes not from ourselves but from the empowering work of the Holy Spirit in our lives. The concept of grace underscores that we are not engaging in mortification to earn salvation or favor with God, but rather, as a response to the grace already bestowed upon us. Thus, mortification is a manifestation of our gratitude for what Christ has done and a commitment to reflecting His holiness.
