Answer
Though today the word baptism generally evokes thoughts of identifying with Christ’s death, burial, and resurrection, baptism did not begin with Christians. For centuries before Christ, the Jews had used bathing in water as a ritual cleansing ceremony (see Leviticus 14:1–4, 8–9; 15:4, 6–11, 13, 16–22, 27; Numbers 19:7). John the Baptist took the ritual of baptism and applied it to those who saw their need for spiritual cleansing in preparation for the arrival of the Messiah. Many believed John’s message and were baptized by him (Matthew 3:5–6). The baptisms John performed had the specific purpose of readying hearts for the coming of the Lord.
In Matthew 3:11, John the Baptist mentions the purpose of his baptisms: “I baptize you with water for repentance.” Paul affirms this in Acts 19:4: “John’s baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus.” John’s baptism had to do with repentance—it was a symbolic representation of changing one’s mind and going a new direction. “Confessing their sins, they were baptized by him in the Jordan River” (Matthew 3:6). Being baptized by John demonstrated a recognition of one’s sin, a desire for spiritual cleansing, and a commitment to follow God’s law in anticipation of the Messiah’s arrival.
There were some, like the Pharisees, who came to the Jordan to observe John’s ministry but who had no desire to step into the water themselves. John rebuked them sternly: “When he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: ‘You brood of vipers! Who warned you to flee from the coming wrath? Produce fruit in keeping with repentance’” (Matthew 3:7–8). Even the religious leaders needed to repent of their sin, although they saw no need of it.
Christian baptism today also symbolizes repentance, cleansing, and commitment, but Jesus has given it a different emphasis. Christian baptism is a mark of one’s identification with the death, burial, and resurrection of Christ. It is representative of a cleansing that is complete and a commitment that is the natural response of one who has been made new. Jesus’ sacrifice on the cross completely washes away our sins, and we are raised to new life empowered by the Holy Spirit (2 Corinthians 5:17–21; Romans 6:1–11). With John’s baptism, a person repented of sin and was therefore ready to place his faith in Jesus Christ. John’s baptism foreshadowed what Jesus would accomplish, much as the Old Testament sacrificial system did.
John prepared the way for Christ by calling people to acknowledge their sin and their need for salvation. His baptism was a purification ceremony meant to ready the peoples’ hearts to receive their Savior.
