Purpose and Process of Sanctification in Christian Life

The point of sanctification is to conform believers to the image of Christ, as Paul writes in Romans 8:28 that God works all things together for the good of those who love Him, to be conformed to the image of His Son. This process of sanctification is necessary because, although God does justify believers instantly at conversion, He does not immediately remove all besetting sins. Instead, He chooses to progressively sanctify His people, setting them apart for His purposes and enabling them to live a life that honors Him.

This ongoing process of sanctification matters because it demonstrates God's patience and love for His children, as He works to mature them in their faith and to bring about lasting change in their lives. It also underscores the reality of human sinfulness and the need for continual dependence on God's grace.

The doctrine of sanctification highlights the importance of the Christian's pursuit of holiness, not as a means of earning salvation, but as a response to the salvation they have already received. It reminds believers that their salvation is not just about being forgiven, but also about being transformed into the likeness of Christ, and that this transformation is a lifelong process that requires effort, perseverance, and trust in God's sovereignty.
