Turning, Trusting, and Immersed: The Role of Repentance and Faith in Baptism

The Foundation of New Life in Christ

Baptism is one of the most powerful outward expressions of the inward transformation that occurs in the heart of a believer. But baptism, in and of itself, is not the starting point of salvation. It is the response to a deeper work that God has already begun—namely, repentance from sin and faith in Jesus Christ. These two elements—repentance and faith—are the spiritual prerequisites for baptism. Without them, baptism becomes an empty ritual rather than a sacred testimony of grace received.

Two key passages in the New Testament help us understand this divine order and the essential connection between heart transformation and baptism.

Acts 2:38
“Then Peter said to them, ‘Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.’”

Galatians 3:26–27
“For you are all sons of God through faith in Christ Jesus.
For as many of you as were baptized into Christ have put on Christ.”

These passages reveal that repentance and faith are not optional steps—they are the doorway into the new life that baptism symbolizes.

Repentance: A Turning Away from Sin Toward God

In Acts 2:38, Peter responds to a crowd deeply convicted by the gospel message. When asked, “What shall we do?” he responds first with, “Repent.” Repentance is more than mere regret or sorrow over sin—it is a decisive turning away from rebellion and a turning toward God in surrender.

Repentance includes:

• A recognition of one’s guilt before a holy God.

• A heartfelt sorrow over sin.

• A willful decision to forsake that sin.

• A desire to walk in obedience and newness of life.

Baptism without repentance is like planting a seed in dry soil—it may be buried, but it will never bear fruit. Repentance prepares the heart to receive the grace of God. It is the soil in which the new life in Christ begins to grow. Baptism, then, becomes the visible declaration of this inward change: “I am done with sin. I am alive to God.”

Repentance is the death of the old self; baptism is the burial.

Faith: Trusting in the Finished Work of Christ

While repentance turns us from sin, faith turns us toward Christ. Galatians 3:26–27 makes the connection between faith and baptism unmistakable:

“For you are all sons of God through faith in Christ Jesus.
For as many of you as were baptized into Christ have put on Christ.”

Faith is the means by which we are united to Christ and adopted into God’s family. It is not merely intellectual agreement—it is wholehearted trust in the person and work of Jesus:

• Trust that His death paid the penalty for our sins.

• Trust that His resurrection secures our new life.

• Trust that His promises are true and eternal.

Faith brings us into union with Christ. Baptism proclaims that union publicly. When a believer is baptized, they are not earning salvation—they are demonstrating that they already believe in the One who saves.

Baptism is not the act that makes us sons and daughters of God. Faith does that. But baptism powerfully illustrates that we now “put on Christ”—we are clothed in His righteousness and covered by His grace.

Baptism: The Visible Seal of an Invisible Reality

In both Acts 2:38 and Galatians 3:27, baptism follows an internal transformation. First comes conviction, then repentance and faith, and then baptism as a visible seal of what has taken place in the heart.

Baptism functions like a wedding ring. The ring does not make the marriage real—the vows do. But the ring testifies to the reality of the covenant. In the same way, baptism testifies to a covenant that has already begun in the heart through repentance and faith.

This is why the early church consistently baptized believers after they had heard and responded to the gospel:

• The Ethiopian eunuch believed, then was baptized (Acts 8:36–38).

• Cornelius and his household received the Holy Spirit, then were baptized (Acts 10:44–48).

• The Philippian jailer believed with his household, then was baptized (Acts 16:30–33).

In each case, faith preceded baptism, not the other way around.

Why Repentance and Faith Must Come First

To baptize someone who has not repented or believed is to offer them a sign without substance—a ceremony without a covenant. Baptism is not a mystical rite that works independently of the heart. It is powerful precisely because it is tied to repentance and faith.

Without repentance, baptism does not symbolize death to sin.
Without faith, baptism does not symbolize union with Christ.

But when both are present, baptism becomes a holy moment of proclamation:

• That the old self has died.

• That Christ now lives within.

• That the person has been raised to walk in newness of life.

Conclusion: A Response, Not a Ritual

Acts 2:38 calls us to repent and be baptized.
Galatians 3:26–27 shows that faith makes us children of God and that baptism reflects our new identity in Christ.

Repentance and faith are the spiritual gateway to salvation; baptism is the physical expression of that transformation. It is not a ritual to be performed without understanding. It is a sacred act of obedience that flows from a heart that has turned from sin and trusted in Christ.

Baptism doesn’t save—but it does proclaim that the person has been saved.
It doesn’t wash the heart—but it declares that the heart has been cleansed.
It doesn’t produce faith—but it powerfully displays it.

True baptism begins not in water, but in the heart—with repentance and faith. And when those two meet the gospel, the result is new life worth declaring to the world.
