The baptism of a believer symbolizes his union with Christ which took place at his conversion (Romans 6:1-6). Because the believer was baptized into Christ, he was also baptized into His death (vs. 3). The believer died with Christ, was buried with Christ, and was raised from the dead with Christ. (Romans 6:4-5) The one who is baptized testifies to the truth that his old sinful way of life has come to an end; it is dead and buried. He has also been raised from the dead and is a new person in Christ. He no longer lives in sin, but has been freed from it, and now walks in newness of life.
