Baptism is intended only for those who have professed faith in Jesus Christ. We baptize by immersion because it is not only the original significance of the word but also best symbolizes the reality to which baptism points—our death and resurrection in Christ.
Baptism is necessary for Christian obedience, and is vital to growth in your Christian walk. We are encouraged to keep Christ’s commandments through baptism:
By the example of Christ.
By the encouragement of New Testament believers. (Acts 8:26–38; 10:47–48; and 16:25–34)
By the explanation of Scripture. (Romans 6:4–5)
