Baptism represents a powerful symbol of an inward change through outward expression, demonstrating a complete U-turn from self-dependence to God-dependence. It involves both confession of our inability to earn salvation and profession of our faith in Jesus Christ. Jesus was baptized not because He needed salvation, but to set an example, illustrate the gospel message, and begin His public ministry. Biblical baptism should be done by full immersion in water after someone has personally trusted Jesus as Savior. Like a wedding ring declares marriage status, baptism publicly declares our relationship with Christ to the world.
