Baptism is an important act of obedience that demonstrates an individual's faith in Jesus for salvation. It symbolizes the washing away of sin and the spiritual rebirth into a new life in Christ. It's an outward sign of an inward spiritual reality. When believers are baptized, they are immersed in water to symbolize their identification with the death and burial of Jesus, and then raised out of the water to symbolize His resurrection.
Baptism is a public declaration of faith in Jesus that affirms a person's decision to follow Christ (Acts 2:41a), to begin a new life in Christ (Romans 6:4), and to become a part of a spiritual family (Galatians 3:26-27).
