Core Pillar - Justification - Repentance from sin

Repentance is one of the most neglected teachings in modern Christianity, even though it stood at the center of the message preached by Jesus, the apostles, and the early church.

Today, repentance is often reduced to an emotional moment, a guilty conscience, or simply feeling bad about sin. In many churches, salvation is presented almost entirely as intellectual agreement with certain truths about Jesus, while repentance is treated as optional or secondary. Yet when we read the New Testament honestly, we find something very different.

Jesus began His ministry with a command:

“Repent, for the kingdom of heaven is at hand.” — Matthew 4:17 (NKJV)

That was not merely an invitation to adopt new religious ideas. It was a call to surrender.

According to Steve Gregg’s teaching in his Foundations of the Christian Faith lectures on repentance, biblical repentance is not superficial remorse or temporary emotional conviction. It is a radical turning of the whole person toward God and away from rebellion, self-rule, and sin.

Repentance is foundational Christianity.

Repentance Is More Than Feeling Sorry

One of the clearest distinctions Gregg makes is the difference between repentance and regret.

Many people regret consequences.

Many feel guilt.

Many experience emotional sorrow.

But repentance is something deeper.

Judas regretted betraying Christ, yet Scripture never presents him as repentant. Esau mourned what he lost, but Hebrews says he found no place for repentance even though he sought it with tears. Emotional pain alone does not equal transformation.

Paul writes:

“For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death.” — 2 Corinthians 7:10 (NKJV)

Godly sorrow may lead a man to repentance, but sorrow itself is not repentance.

Biblical repentance means a man stops defending his sin. He stops justifying rebellion. He stops living as though he owns his own life.

The Greek word metanoia literally means a change of mind, but in Scripture that change reaches far beyond intellectual adjustment. True repentance changes direction, loyalties, priorities, and conduct.

A repentant man may still struggle with weakness, but his posture toward sin has changed. He is no longer at peace with it.

Repentance is directional before it is developmental.

The Gospel Demands Repentance

Modern Christianity often presents Jesus as an addition to someone’s existing life rather than the rightful King over it.

But Jesus never preached:
“Invite Me into your heart so nothing changes.”

He preached:

“If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me.” — Luke 9:23 (NKJV)

That language is not casual. It is covenantal.

Repentance means yielding ownership of your life to Christ. It means abandoning autonomous living and submitting to the authority of the King.

This is why repentance and faith cannot be separated.

Hebrews 6 places them together:

“repentance from dead works and of faith toward God” — Hebrews 6:1 (NKJV)

A man cannot genuinely trust Christ while clinging to rebellion against Him. At the same time, repentance without faith simply becomes moral striving and religious self-effort.

Biblical conversion includes both:

• turning away from sin,

• and turning toward Christ.

Not merely modifying behavior, but transferring allegiance.

Repentance From Dead Works

Gregg also highlights the phrase “dead works” from Hebrews 6.

Most people assume dead works only refers to obvious sinful behavior, but Scripture goes deeper than that. Dead works also include empty religious activity, self-righteousness, and attempts to justify oneself apart from obedient faith.

This is important because many people hide spiritual deadness behind religious appearance.

A church service cannot substitute for obedience.

Bible knowledge cannot substitute for surrender.

Religious culture cannot substitute for transformation.

Jesus rebuked religious men constantly because they honored God outwardly while remaining inwardly rebellious.

Repentance tears down both open sin and spiritual pride.

Repentance Produces Fruit

John the Baptist warned Israel:

“Bear fruits worthy of repentance.” — Luke 3:8 (NKJV)

Repentance begins internally, but it eventually becomes visible externally.

A changed heart produces changed living.

That does not mean instant perfection. Scripture never teaches sinless maturity the moment someone comes to Christ. But it does teach transformation.

A repentant person begins pursuing reconciliation instead of bitterness. He becomes teachable instead of defensive. He starts seeking holiness instead of excusing compromise. His trajectory changes because his allegiance has changed.

This is one of the great missing elements in modern “decision-based” Christianity.

The New Testament never treats salvation as merely repeating words or agreeing with facts. Genuine faith produces obedience because genuine faith submits to Christ as Lord.

As James writes:

“Faith without works is dead.” — James 2:26 (NKJV)

Not because works save us, but because living faith transforms us.

Repentance Is Ongoing

Repentance is not merely something that happens at conversion and never again.

The Christian life is a continual response to the conviction and correction of the Holy Spirit.

As believers mature, God reveals deeper pride, deeper compromise, deeper selfishness, and deeper areas requiring surrender.

This ongoing repentance protects believers from complacency and hypocrisy. It keeps the heart soft before God.

A healthy Christian does not become less repentant over time.

He becomes more sensitive to sin and more responsive to God.

Cheap Grace Cannot Produce Disciples

One of Gregg’s strongest warnings concerns what many call “easy-believism.”

Modern churches often promise salvation without transformation, grace without obedience, and faith without surrender. But the gospel preached by Jesus and the apostles never separated grace from discipleship.

Grace is not permission to remain unchanged.

Grace is the power that enables transformation.

Paul wrote:

“For the grace of God that brings salvation has appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age.” — Titus 2:11–12 (NKJV)

Biblical grace teaches holiness.

It teaches obedience.

It teaches surrender.

Repentance is therefore not legalism. It is the evidence that a man has truly encountered the authority and mercy of God.

The Kingdom Issue

At its core, repentance is about rulership.

Who rules your life?

That is the issue Jesus continually confronted.

The gospel is not simply about avoiding judgment after death. It is about entering the Kingdom of God now under the reign of Christ.

Repentance means transferring allegiance from self-rule to God’s rule.

It is relational.

It is covenantal.

It is governmental.

And this is exactly why repentance remains foundational to authentic Christianity.

Without repentance, Christianity becomes cultural religion.

Without repentance, churches become institutions full of spectators.

Without repentance, men continue claiming Christ while remaining slaves to the world.

But where true repentance exists, transformation follows.

Not perfection overnight.

But a genuine turning toward God that reshapes the direction of a man’s life.
