The Holy Spirit works through humans in baptizing in water expressing faith in Jesus' death, burial, resurrection.
If you haven't been baptized in water then you haven't died to walk in newness of life with Christ.
Romans 6:4 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.
Galatians 3:27 For as many of you as were baptized into Christ have put on Christ.
There's only "ONE" baptism today, and that is when the Holy Spirit baptizes a believer into the Body of Christ.
