How does the doctrine of sanctification shape the Christian life? Offering a fully developed treatment of "accomplished" sanctification, Don Payne explains that the primary biblical focus in sanctification is not progressive growth but that which has already occurred for Christians to make growth possible, necessary, and grace-driven. As Payne explores the significance Scripture attributes to the accomplished aspect of sanctification, he helps us understand that we are already sanctified. Sanctification is not synonymous with transformation but undergirds strategies and resources related to Christian discipleship and formation.
