Read Romans 8:9–13.
Sanctification is the progressive work of God and believers that makes us more and more free from sin and like Christ in our actual lives.
This passage tells us that if we have the Holy Spirit dwelling in us, then we are not controlled by the flesh but by the Spirit. The Holy Spirit gives us life and righteousness. And through his power, we can overcome the sin that once controlled us.
But sanctification is not something that happens overnight. It is a progressive work, a journey of becoming more and more like Christ. It is a process of being transformed and conformed to the image of Christ, of putting off the old self and putting on the new self.
As we seek sanctification by the Holy Spirit, let us pray for his guidance and strength. Let us also be diligent in our efforts to grow in our faith, reading the Word of God and seeking the counsel of other believers. May we be obedient to the leading of the Holy Spirit, and may we allow him to work in our lives, making us more and more like Christ.
