Water baptism is the act of being immersed in water according to the commandment and instructions of Christ (Matthew 28:19). This ordinance has no power to wash away sins, but is the answer of a good conscience toward God (1 Peter 3:21) and represents for the believer an identity with the death, burial, and resurrection of our Lord (Romans 6:3–5). Mark 16:16 further reinforces the necessity of this step of obedience: “He that believeth and is baptized shall be saved but he that believeth not shall be damned.” On the day of Pentecost, the apostle Peter told those under conviction what they should do: “Repent and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost” (Acts 2:38). Obviously, the apostles literally followed the Lord’s instructions, and we can do no less. Baptism, then, is outward evidence of our submission to Christ in salvation and our public declaration that we are His followers. It identifies us with His people in His kingdom. “Then they that gladly received His word were baptized: and the same day there were added unto them about three thousand souls” (2:41; see also 10:47, 48 and 16:30–33).
