Romans 6:3-5 3 - …Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? 4 - 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. 5 - For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection… This passage presents several problems to those who do not see it as Spirit baptism. First, water baptism does not unite a person into the death of Christ. No earthly work can unite a person to Christ. Second, this passage gives a foundation to overcome sin (v.5). Water baptism cannot do that. Third, (this is huge) if water baptism is involved, than baptismal regeneration CANNOT be denied. More could be said, but this should be sufficient for now.
