Baptism is a symbolic, public, and outward expression of the salvation Jesus has provided. After you have put your trust in Jesus for the forgiveness of your sins, baptism is a great next step. It is important to remember that baptism is not a requirement for your salvation. Water baptism is, however, a command from Jesus for every disciple, so it is a great thing that you are exploring it now.
Baptism is very symbolic. It is a symbol of how our sins have been washed away. Immersion in the water represents our renewal and cleansing through what Jesus did on the cross. It is also a picture of the death of our old self and how we are raised into new life, just like Jesus was buried and brought back to life again.
