Baptism was practiced before the founding of the church. The Jews of ancient times would baptize proselytes to signify the converts’ “cleansed” nature. John the Baptist used baptism to prepare the way of the Lord, requiring everyone, not just Gentiles, to be baptized because everyone needs repentance. However, John’s baptism, signifying repentance, is not the same as Christian baptism, as seen in Acts 18:24–26 and 19:1–7. Christian baptism has a deeper significance.
Baptism is to be done in the name of the Father, Son, and Spirit—this is what makes it “Christian” baptism. It is through this ordinance that a person is admitted into the fellowship of the church. When we are saved, we are “baptized” by the Spirit into the Body of Christ, which is the church. First Corinthians 12:13 says, “We were all baptized by one Spirit so as to form one body—whether Jews or Gentiles, slave or free—and we were all given the one Spirit to drink.” Baptism by water is a “reenactment” of the baptism by the Spirit.
Christian baptism is the means by which a person makes a public profession of faith and discipleship. In the waters of baptism, a person says, wordlessly, “I confess faith in Christ; Jesus has cleansed my soul from sin, and I now have a new life of sanctification.”
Christian baptism illustrates, in dramatic style, the death, burial, and resurrection of Christ. At the same time, it also illustrates our death to sin and new life in Christ. As the sinner confesses the Lord Jesus, he dies to sin (Romans 6:11) and is raised to a brand-new life (Colossians 2:12). Being submerged in the water represents death to sin, and emerging from the water represents the cleansed, holy life that follows salvation. Romans 6:4 puts it this way: “We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.”
Very simply, baptism is an outward testimony of the inward change in a believer’s life. Christian baptism is an act of obedience to the Lord after salvation; although baptism is closely associated with salvation, it is not a requirement to be saved. The Bible shows in many places that the order of events is 1) a person believes in the Lord Jesus and 2) he is baptized. This sequence is seen in Acts 2:41, “Those who accepted [Peter’s] message were baptized” (see also Acts 16:14–15).
A new believer in Jesus Christ should desire to be baptized as soon as possible. In Acts 8 Philip speaks “the good news about Jesus” to the Ethiopian eunuch, and, “as they traveled along the road, they came to some water and the eunuch said, ‘Look, here is water. What can stand in the way of my being baptized?’” (verses 35–36). Right away, they stopped the chariot, and Philip baptized the man.
Baptism illustrates a believer’s identification with Christ’s death, burial, and resurrection. Everywhere the gospel is preached and people are drawn to faith in Christ, they are to be baptized.
