Practical Applications of the Doctrine of Sanctification
Sanctification, the process by which believers are made holy, has several practical applications in Christian life, touching upon moral conduct, spiritual growth, and separation for divine service [1, 2]. It is not merely a moral reformation but a work of the Holy Spirit that brings the entire person under the influence of new, gracious principles implanted during regeneration [1].
One primary application of sanctification is the mortification of sin and the pursuit of holiness in daily life [9]. The apostle Paul, in Romans 6, addresses the concern that the doctrine of justification by faith might lead to continued sin. He emphatically rejects this idea, stating that believers should not "continue in sin that grace may abound" [8]. Instead, sanctification is presented as an "absolute necessity" and an "inseparable fruit and companion of justification" [12]. This means that a genuine experience of salvation through Christ inevitably leads to a desire and effort to live a holy life, characterized by a turning away from sin [9].
Sanctification also involves a separation to the service of God [2]. This concept is rooted in the Old Testament idea of purification, where individuals or objects were set apart for sacred use [5]. In the New Testament, Jesus himself prayed for his disciples, "Sanctify them through thy truth, thy word is truth," indicating a desire for their consecration and moral purity [4, 6]. John Gill notes that this separation implies that believers are "not of the world," even as Christ was not of the world, and this distinction exposes them to the world's animosity [10]. The practical outworking of this separation is seen in believers being equipped to serve God, with Christ himself sanctifying or consecrating himself for their sakes, so they too might be consecrated [7].
Furthermore, sanctification is understood as a continuous work of the Holy Spirit, leading to spiritual maturity and perfection [1]. It extends to the "whole man" and is carried on to perfection, implying an ongoing process of growth in grace [1, 3]. This ongoing work is evident in the call to "sanctify Christ as Lord" in one's heart, honoring Him as holy and allowing His holiness to be glorified through the indwelling Spirit [11]. The practical implication is a life dedicated to growing in conformity to Christ, guided by God's Word [2, 6].

In other words, sanctification is the carrying on to perfection the work begun in regeneration, and it extends to the whole man (Rom. 6:13; 2 Cor. 4:6; Col. 3:10; 1 John 4:7; 1 Cor. 6:19). It is the special office of the Holy Spirit in the plan of redemption to carry on this work (1 Cor. 6:1”

But in the details of daily life there were special causes of cermonial uncleanness which were severally provided for by ceremonial laws enacted for each separate case.

The only difference between the application of the same term to Christ and the disciples is, as applied to Christ, that it means only to "consecrate"; whereas, in application to the disciples, it means to consecrate with the additional idea of previous sanctification, since nothing but what is holy can be presented as an offering. The whole self-sacrificing work of the disciples appears here as a mere result of the offering of Christ [OLSHAUSEN]”

Shall we hence take encouragement to sin with so much the more boldness, because the more sin we commit the more will the grace of God be magnified in our pardon? Is this a use to be made of it?"

"Sanctification" is internal or external.
