Work in Sanctification

God’s ongoing work of making believers holy in heart and conduct. Christians actively obey, but this growth ultimately depends on God’s grace and the Spirit’s power.

At a Glance

Sanctification is the process and work of becoming holy. In the New Testament it includes both a definitive setting apart to God in Christ and a progressive growth in holiness throughout the Christian life.

Key Points

Description

Sanctification is the continuing work of God in the life of a believer by which He increasingly sets the believer apart from sin and forms Christlike character and obedience. In the New Testament, sanctification includes both a definitive aspect, in which believers are set apart to God in Christ, and a progressive aspect, in which they grow in holiness through the Spirit, the Word, prayer, repentance, fellowship, and obedient faith. Scripture holds together divine agency and human responsibility: God works in His people, and believers are commanded to pursue holiness and put sin to death. Sanctification does not earn salvation and must be distinguished from justification, yet it is a real and necessary fruit of saving faith.

Biblical Context

The Bible presents holiness as God’s own character and as His purpose for His people. In the New Testament, believers are called saints and are exhorted to live in a way that matches their calling. Sanctification is therefore both status and process: God has set believers apart in Christ, and He continues to transform them in daily life.

Historical Context

Christian theology has long distinguished sanctification from justification while also insisting that the two cannot be separated in a living Christian experience. Evangelical traditions have generally emphasized progressive sanctification as the ordinary pattern of growth after conversion, though they differ on the pace, crisis moments, and means of growth.

Jewish and Ancient Context

In the Old Testament background, holiness means being set apart for God’s use and purity. Israel’s priests, objects, and feasts could be sanctified, showing that sanctification is fundamentally about belonging to God and being consecrated for His purposes.

Original Language Note

The main biblical terms behind sanctification are the Hebrew idea of being set apart as holy and the New Testament Greek word group related to holiness and consecration.

Theological Significance

Sanctification shows that salvation produces real moral change. It guards against both legalism, which treats holiness as the basis of acceptance with God, and antinomianism, which denies the necessity of obedient growth. It also emphasizes that Christian maturity comes through God’s power working in and through the believer.

Philosophical Explanation

Sanctification reflects a moral and relational transformation rather than merely external rule-keeping. The believer’s will is truly engaged, but its obedience is enabled by divine grace. Christian growth is therefore personal, gradual, and dependent on God’s action without reducing human responsibility.

Interpretive Cautions

Do not confuse sanctification with justification, adoption, or glorification. Do not treat sanctification as self-improvement by willpower alone. Avoid making every believer’s growth pattern identical; Scripture presents real growth, but not always in the same pace or form.

Major Views

Evangelicals agree that sanctification is necessary and Spirit-enabled, but differ on whether a decisive crisis of entire sanctification is expected, how strongly to stress instantaneous deliverance from certain sins, and how to describe the believer’s ongoing struggle with sin.

Doctrinal Boundaries

Sanctification is the fruit of salvation, not the ground of it. It is grounded in union with Christ, empowered by the Holy Spirit, and expressed in obedience. It should not be used to deny assurance to struggling believers or to make holiness optional for professing Christians.

Practical Significance

This doctrine encourages believers to pursue repentance, prayer, Scripture reading, accountability, and Spirit-led obedience. It also gives hope that growth is possible because God is at work in His people.
