Baptism by immersion symbolizes the death, burial, and resurrection of Jesus and is your public declaration that you have accepted Jesus Christ as your personal Savior. Baptism does not save you, but shows the world that you have already been saved. And while baptism is not required for salvation, it is a biblical command and demonstrates your love and obedience to Christ.
