Faith and Sanctification in Christian Theology

Sanctification is the process by which believers are set apart for God's service and progressively conformed to his will, moving towards holiness [1, 2, 7]. It is distinct from mere moral reformation, being a work of the Holy Spirit that influences the entire person [1]. This process is understood as the continuation and perfecting of the work initiated in regeneration [1].

The concept of sanctification is deeply rooted in biblical texts. The Apostle Paul, for instance, speaks of believers being "sanctified in Christ Jesus" (1 Corinthians 1:2) and urges them to present their bodies as instruments of righteousness, leading to sanctification (Romans 6:19, 22). The process involves the entire being (1 Thessalonians 5:23) and is described as a gradual development [7]. The Bible also connects sanctification to God's word and prayer, as seen in 1 Timothy 4:5, which states that "it is sanctified through the word of God and prayer" [3, 4].

Several agents are identified in the work of sanctification:

Sanctification is often understood as a separation to God's service (Psalm 4:3; 2 Corinthians 6:17) [2]. It is also linked to holiness, which in its highest sense belongs to God, and is applied to Christians as they are consecrated to God's service and conform to his will (Romans 6:19, 22; Ephesians 1:4; Titus 1:8; 1 Peter 1:15) [7]. This personal holiness is not an instantaneous event but a process that requires watchfulness, prayer, and perseverance due to various hindrances (1 Corinthians 1:30; 2 Corinthians 7:1; Ephesians 4:23, 24) [7].

The relationship between faith and sanctification is significant. Faith is not merely a passive assent but a "working reality" that manifests itself through its fruits [9]. This "work of faith" is seen as a continuous chain of activity, leading to its full development [9]. The Jamieson, Fausset & Brown commentary on 1 Thessalonians 1:3 describes faith as active and producing work [9]. The outcome of sanctification is a life that glorifies God (1 Corinthians 6:20) [6].

While sanctification is a divine work, it also calls for human participation, particularly in the mortification of sin (1 Thessalonians 4:3, 4) [2]. The goal is to achieve a state of perfection, which is closely related to sanctification [5]. This ongoing process ensures that the Church is made glorious (Ephesians 5:26, 27) [2].

Easton's Bible Dictionary “Easton's Bible Dictionary: Sanctification — Involves more than a mere moral reformation of character, brought about by the power of the truth: it is the work of the Holy Spirit bringing the whole nature more and more under the influences of the new gracious principles implanted in the soul in regeneration. 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”

Personal holiness is a work of gradual development. It is carried on under many hindrances, hence the frequent admonitions to watchfulness, prayer, and perseverance (1 Cor. 1:30; 2 Cor. 7:1; Eph. 4:23, 24). (See [280]SANCTIFICATION.)”
