HOLINESS AND SANCTIFICATION

“Pursue peace with all men, and the sanctification without which no one will see the Lord.” (Hebrews 12:14, LSB)

The modern evangelical church is infected with a fatal theological disease: Antinomianism (literally, “anti-law”). It is the grotesque proposition that the grace of God exists to pardon sin while leaving the sinner entirely untransformed. Under the banner of hyper-grace, millions have been falsely assured that they can possess justification in the courtroom of heaven while their daily lives remain indistinguishable from the pagan world.

This is a damning severing of the work of Christ. The God of the Bible does not merely declare dead men to be legally righteous; He surgically replaces their nature, granting them the ontological capacity and the unbreakable mandate to actively pursue holiness. Justification and sanctification are distinct, but they are absolutely inseparable. You cannot have the blood of Christ to save you without the Spirit of Christ to conquer you.

We are bringing the doctrine of sanctification back under the severe, unrelenting light of the Greek text. We will dismantle the psychological excuse of the carnal Christian and recover the biblical theology of mortification.

The English word “sanctification” is a translation of the Greek noun ἁγιασμός (hagiasmos), derived from the root ἅγιος (hagios), meaning holy. In the ancient world, to be hagios was to be violently severed from common, profane use and dedicated exclusively for sacred, divine ownership.

When applied to the believer, sanctification is not a suggestion for spiritual elites; it is the fundamental trajectory of every regenerate soul. First Thessalonians 4:3 states unequivocally: “For this is the will of God, your sanctification; that is, that you abstain from sexual immorality.” (1 Thessalonians 4:3)

God does not save a man to leave him in the pigpen of his depravity. The blood of the covenant was shed to purchase a holy people. If there is no separation from the world, there is no evidence of the new birth.

In the 20th century, a disastrous theology emerged from the dispensational movement, popularizing the concept of the Carnal Christian. This framework argued that a person could receive Jesus as Savior, but entirely reject Him as Lord, remaining permanently trapped in a state of unrepentant sin (the “carnal” state) while still guaranteeing their ticket to heaven. This was built upon a violent misinterpretation of 1 Corinthians 3.

The Apostle Paul completely annihilates this category in Romans 8. The biblical text divides all of humanity into only two ontological categories: those in the flesh (σαρκικός – sarkikos) and those in the Spirit (πνευματικός – pneumatikos).

The text is absolute. You cannot be a “carnal” Christian in the sense that your fundamental nature is governed by the flesh. If the Holy Spirit resides in you, the dominion of the flesh is broken. Christians battle the flesh; they fall into sin, but they do not reside comfortably under its dictatorship. A person who lives in unbroken, unrepentant carnality is not a “struggling Christian”; they are an unregenerate enemy of God.

To understand sanctification without falling into legalism or works-righteousness, we must rightly divide its two biblical aspects: Positional and Progressive. The writer of Hebrews brilliantly juxtaposes these two realities within four verses of each other.

Positional Sanctification: The moment you are justified, you are definitively, irreversibly set apart by the blood of Christ. You are declared holy. The verb in Hebrews 10:10 is in the perfect tense a completed past action with ongoing eternal results.

Progressive Sanctification: Hebrews 10:14 uses a present participle (are being sanctified). Because God has declared you holy positionally, the Holy Spirit now works actively to make you holy practically. Progressive sanctification is the synergistic reality where the sovereign power of God fuels the violent, active obedience of the believer (Philippians 2:12-13).

The pursuit of holiness is not a passive surrender. The popular charismatic phrase “Let go and let God” is found nowhere in the Apostolic canon. The New Testament commands an aggressive, calculated war against remaining sin.

“Do you mortify? Do you make it your daily work? Be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you.” JOHN OWEN // Of the Mortification of Sin in Believers (1656)

The Apostle Paul lays out the mechanics of this war in Romans 8:13: “For if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live.”

The Greek verb is θανατοῦτε (thanatoute) to execute, to put to death. It is a present active imperative. You are commanded to continually act as the executioner of your own sinful desires. Notice the mechanics: you do not defeat sin by human willpower or monastic rules. You put to death the deeds of the body by the Spirit. The Spirit supplies the power, but the believer must wield the sword.
