When we are saved, we are “baptized” by the Spirit into the Body of Christ, which is the church. 1Corinthians 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 “re enactment” of the baptism by the Spirit.
When a person is baptised they are making a public profession of faith and discipleship. In the waters of baptism, a person states that they believe that Jesus Christ is the Son of God and that he died and rose again so that their sins can be forgiven.They also state that they have accepted Jesus Christ as their Saviour.
Christian baptism illustrates, 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 a testimony of the 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,
Baptism illustrates a believer’s identification with Christ’s death, burial, and resurrection. Everywhere the gospel is preached, people are to be baptized.
