Why Be Baptized?
Baptism shows others you have made the decision to follow Jesus, and are trusting him for salvation. Jesus was baptized when he was on earth, and we do this to follow his example.
When Christians are baptized, they are submerged under water to identify with the death and burial of Jesus and raised out of the water to identify with His resurrection. Baptism is a public declaration of three important things: you are a follower of Jesus, you are beginning a new life in Christ, and you are a part of a new family.
