Christian baptism began after the church was established and after Peter preached on Pentecost (Acts 2:38–41). From that point forward, baptism became the typical response of those who believed in Jesus (Acts 8:12, 36–38; 9:18; 10:47–48). In this sense, Christian baptism originates with the birth of the church.
At the same time, the act of baptism was not entirely new. Before the church began, John the Baptist had already been calling people to repentance and baptizing them as a sign of confessed sin and preparation for the coming Messiah (Mark 1:4–5). John’s baptism was not Christian baptism, but it prepared the people for it by using water as a public expression of repentance.
His practice likely drew on earlier practices. For example, during the intertestamental period, Jewish communities were already familiar with ritual washings and immersions connected to purity and repentance. Though some attempt to connect those activities to Levitical practices in Leviticus 16:23–24, it’s hard to affirm or verify that connection since they were such distinct practices.
Our world is filled with behaviors that communicate meaning: A thumbs up means approval. A finger to the lips means be quiet. A shrug means “I don’t care” or “I don’t know.”
For Christians, baptism is one of the most important behaviors; it says, “I serve Christ rather than sin.” Baptism doesn’t save, but it visibly declares what God has already done in a believer’s heart. Scripture presents baptism as a picture of our union with Christ. Going into the water reflects being buried with Him, and coming out of the water reflects being raised to new life (Romans 6:3–4). This act proclaims that Jesus’ death counts as the believer’s death to sin and that His resurrection is now the source of their new life. Baptism, therefore, points away from the individual and toward Christ’s saving work.It publicly displays the reality of salvation that comes through faith in Jesus Christ.
Baptism also marks entrance into the visible community of believers. It is a step of obedience that follows faith and connects the believer to the church, the body of Christ. Through baptism, a Christian declares loyalty to Jesus and fellowship with His people.
Have you trusted Christ but have not yet been baptized? If not, why wait? Your baptism is a way to give glory to the Savior who brought you from death to life.
