Baptism is a beautiful picture of what our Lord and Savior has done for us. Being completely submersed in water symbolizes the burial of the old man, the washing over top of us with water symbolizes the washing away of our sins, and the rising out of the water symbolizes the resurrection of the new man arising and walking forth.
“Or you do not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection, knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin. For he who has died has been freed from sin.” (Romans 6:3-7)
Jesus Himself was baptized prior to His death and resurrection by John the Baptist. With His own baptism, He
foreshadowed the death and resurrection that was to come.
Following Jesus example, we too should be baptized in water. Not only is it symbolic, but it also publicly expresses the change that has taken place in our lives. Inside of us, we have laid down our old self and asked forgiveness of our sins. Jesus blood has cleansed us and made us a new person in Christ. Water baptism allows us an avenue to outwardly show what has taken place inwardly.
