Introduction
Baptism is a public act, done with water, by which a person declares that they follow Jesus Christ. It expresses the forgiveness they have received and a new life. In the Bible, Jesus himself was baptized, and he then asked his disciples to baptize those who believe in him.
Baptism is one of the oldest and most visible practices in Christianity, yet many people do not know where it comes from or what it means. This page explains the meaning of the word, traces its origin in the Bible, presents the essential passages and answers the questions people ask most often.
What does the word baptism mean in the Bible?
The word “baptism” comes from the Greek baptizō, which means to plunge or immerse, the way you dip a piece of cloth into dye. In everyday language of that time, it described a very concrete action: dipping an object in water to wash it or color it.
In the Bible, this ordinary meaning takes on a spiritual weight. The water is not magic. It serves as a visible sign of something unseen: a person is washed clean of their past, turns in a new direction and begins a new life with God. Baptism is first of all a language, a public way of showing what has happened in the heart.
What the Bible says about baptism
Here are the most important passages, in the order the story unfolds: John the Baptist prepares the way, Jesus is baptized, then the first Christians practice baptism.
Matthew 3:11
"I indeed baptize you in water for repentance, but he who comes after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you in the Holy Spirit."
John, called the Baptist, plunges into the water those who recognize their wrongs and want to change their lives. He announces that someone greater is coming, whose baptism will be of a different kind: one of the Spirit. Read all of Matthew 3.
Matthew 3:16-17
"Jesus, when he was baptized, went up directly from the water: and behold, the heavens were opened to him. He saw the Spirit of God descending as a dove, and coming on him. Behold, a voice out of the heavens said, “This is my beloved Son, with whom I am well pleased."
Jesus has just been baptized, although he has no wrongs to confess, in solidarity with human beings. At that moment, the Father's voice and the presence of the Spirit are made visible: baptism is a moment when God reveals himself. Read all of Matthew 3.
Matthew 28:19
"Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,"
Before leaving his disciples, Jesus gives them a mission: make disciples among all nations and baptize them. Baptism thus becomes the doorway into the Christian life, everywhere in the world. Read all of Matthew 28.
Acts 2:38
"Peter said to them, “Repent, and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of sins, and you will receive the gift of the Holy Spirit."
On the day of Pentecost, the first great gathering of the disciples, Peter calls the crowd to change their hearts and be baptized. Baptism is linked to the forgiveness of sins, meaning the wrongs that separate people from God, and to the gift of the Spirit. Read all of Acts 2.
Romans 6:3-4
"Or don’t you know that all we who were baptized into Christ Jesus were baptized into his death? We were buried therefore with him through baptism into death, that just as Christ was raised from the dead through the glory of the Father, so we also might walk in newness of life."
Paul sees in immersion an image of Jesus' burial and then his resurrection. The person who is baptized symbolically leaves the old life behind and rises to live a new one. Read all of Romans 6.
Galatians 3:27
"For as many of you as were baptized into Christ have put on Christ."
Baptism is compared to putting on clothing: the baptized person takes on the identity of Christ. From then on, they belong to a spiritual family that reaches beyond origin, language and culture. Read all of Galatians 3.
John's baptism and Jesus' baptism: what is the difference?
John's baptism was a baptism of repentance. In the Bible, repentance is more than regret: it is a change of direction, a U-turn. People went down to the Jordan, a river in the region, to tell God that they wanted to turn the page.
Christian baptism takes up this act and gives it a broader meaning. It still speaks of repentance, but it is now tied to the death and resurrection of Jesus and to the promise of the Spirit. John himself said so: his role was to prepare the way, not to replace it.
Who can be baptized, and how?
In the New Testament accounts, baptism follows the decision to believe. Adults hear the message of Jesus, embrace it, and then are baptized. Many Christian communities conclude from this that baptism is meant for people who freely choose to follow Jesus.
Christian traditions do not all think alike. Some also baptize the children of believers, seeing it as a sign of God's promise to the family, and the child later confirms their own choice as they grow up. As for the method, some fully immerse the person in water, while others pour water over the head or sprinkle it. Both approaches seek to remain faithful to the Bible.
Common misconceptions about baptism
First misconception: believing that water washes by itself. The Bible presents baptism as an expression of faith and of the forgiveness God gives, not as an automatic ritual that works without the person's trust.
Second misconception: thinking you must be perfect to be baptized. On the contrary, people are baptized precisely because they recognize their limits and receive a forgiveness they cannot give themselves.
Third misconception: seeing baptism as just a family party. It can be followed by a celebration, but at its heart it remains a personal commitment to God.
Living out your baptism day to day
Remember your baptism as a starting point. On hard days, remember that your identity rests on what God says about you, not on your failures.
Join a community. Baptism is not an isolated act: in the Bible, it connects the person to other believers, with whom they learn, pray and support one another.
Keep walking. Paul speaks of “newness of life.” In practice, this shows up in concrete choices: granting forgiveness, giving up a habit, making time for prayer and Bible reading.
If you have not yet been baptized and would like to be, talk with a leader in a Christian community near you. They will explain how to prepare.
