Water baptism involves full immersion in water and symbolizes dying to the old sinful self and being resurrected to a new life in Christ. It is an act of obedience commanded by Jesus to be done after repenting from sins and having faith. In the early church, baptism typically followed salvation and preceded baptism in the Holy Spirit. To be baptized one must repent of sins, have faith in Jesus, and confess belief that He is the Son of God.
