Once a person admits that he or she is a sinner and turns to Christ for salvation, the Bible says that a person should proclaim the life change that has occurred; the watching world needs to know. Baptism has always stood as a kind of public testimony for people who have become believers.

Believers are those who have realized that their sin has separated them from God. They have given up all efforts to reach God through good works or religious activity. They have concluded that Jesus Christ's death on the cross for their sins is the only thing that can bridge the gap between them and God. A believer is someone who has decided to trust Christ alone for his or her salvation.

If you have come to this point in your spiritual journey, then you are ready to be baptized.

According to the Scriptures, the proper mode of baptism is immersion. Jesus, when He was baptized, went up straightway out of the water (Matthew 3:16). Philip and the eunuch both went down into the water, and Philip baptized him (Acts 8:38). Paul writes that we are buried with Him by baptism into death (Romans 6:4). A corpse is not buried by placing it on top of the ground and sprinkling a little soil on it; rather, it is covered completely.

Repentance identifies us with the death of Christ, and baptism identifies us with His burial. Coming forth from the watery grave of baptism and receiving new life in the Holy Spirit identifies us with His resurrection.

Jesus commanded His disciples to teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost (Matthew 28:19). Luke 24:45–47 records that just before His ascension, Jesus opened the disciples' understanding so that they could grasp the vast importance of the death, burial, and resurrection of Christ.

Christian water baptism is an ordinance instituted by Jesus Christ. If it is not important in the plan of God, why did Jesus command it in Matthew 28:19? Why did Peter follow up by saying, "Be baptized every one of you," and by commanding the Gentiles to be baptized (Acts 2:38; 10:48)?

We must remember two points about the importance of water baptism. First, whatever Christ definitely established and ordained cannot be unimportant, whether we understand its significance or not. Second, Christ and the apostles showed the importance of this ordinance by observing it. Jesus walked many miles to be baptized, though He was without sin, saying that it was fitting to fulfill all righteousness (Matthew 3:13–16).

It is true that water itself does not contain any saving virtue. God has chosen to include it in His plan of salvation. Peter explained that baptism saves us, not as the putting away of the filth of the flesh, but as the answer of a good conscience toward God, by the resurrection of Jesus Christ (1 Peter 3:21).
