Sanctification is the lifelong work of God in the believer — the patient, real, sometimes painful process of being shaped into the likeness of Jesus Christ. It is not optional. It is not instant. It is not earned. It is the inevitable fruit of a real salvation. At Grace Fellowship Church in Sarasota, we will not separate the gospel that justifies a sinner from the gospel that makes that sinner holy.
“Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.” — 1 Thessalonians 5:23
The word “sanctify” means to set apart — to consecrate, to make holy. In the New Testament, it has both a settled and an ongoing sense. Settled: every believer has already been sanctified, set apart for God, by the blood of Christ (“you were sanctified… in the name of the Lord Jesus and by the Spirit of our God,” 1 Corinthians 6:11). Ongoing: every believer is being sanctified, increasingly conformed to Christ, day by day, by the Holy Spirit (2 Corinthians 3:18).
Sanctification is not the believer climbing toward God by self-discipline. It is God, by His Spirit, applying the cross to every corner of the believer’s life — the conscience, the affections, the will, the mouth, the body. What was nailed to the cross with Christ (Romans 6:6) is being progressively put off in actual experience.
This is why a Christian is never the same as a non-Christian, even on a bad day. The Christian is a person in whom the Spirit of God lives, and the Spirit will not leave the believer the way He found him.
“The fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control” (Galatians 5:22–23). Holiness is not bolted onto the Christian from the outside. It grows out of the indwelling Spirit, who is the One actually making us holy.
“Work out your own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure” (Philippians 2:12–13). God works; therefore the Christian works. Effort matters. Discipline matters. The Christian is not passive, but the Christian is also not the source.
Sanctification is mysterious in its source but surprisingly ordinary in its means. The Spirit uses what God has put into His people’s hands. He sanctifies through Scripture: “Sanctify them by Your truth. Your word is truth” (John 17:17). He sanctifies through prayer, in which the believer brings every fear, sin, and decision into the light. He sanctifies through the church, where the body of Christ stirs up love and good works in one another (Hebrews 10:24).
He sanctifies through obedience — the small daily yes to what God has said and the small daily no to what He has not. He sanctifies through suffering, which strips off illusions and produces character (Romans 5:3–4). He sanctifies through the loving discipline of the Father, who refuses to leave us where we are (Hebrews 12:10). And He sanctifies through the Lord’s Supper, where the cross is preached again to our deepest places.
None of these are mechanical. All of them are means in the hand of the Spirit, who is the actual sanctifier.
“Pursue peace with all people, and holiness, without which no one will see the Lord.” — Hebrews 12:14
Sanctification is one of the easiest doctrines for Christians to distort. On one side is perfectionism — the idea that with enough effort, surrender, or experience, the Christian will reach a state of sinless living in this life. The Bible refuses this (1 John 1:8). The most mature believer is the one most aware of indwelling sin, not least aware of it.
On the other side is antinomianism — the idea that since we are saved by grace, holiness does not matter and effort is suspect. The Bible refuses this just as flatly. “Shall we continue in sin that grace may abound? Certainly not!” (Romans 6:1–2). Grace produces holiness. Where there is no growth in holiness, there is reason to wonder whether there has been any real grace (Hebrews 12:14).
At Grace Fellowship Church in Sarasota, we hold both: salvation is finished at the cross, and salvation produces a real, daily, often slow transformation. The same Jesus who justifies us is the One who sanctifies us. We trust Him for both.
