(NOT JUST ONCE AT THE TIME OF SALVATION)
1. First, priests and dedicated Jews (that includes the Natsarim) should immerse themselves for the maintenance of ceremonial cleanliness based upon the following circumstances:
A. If a woman has a monthly period.
B. If a man has an emission of semen.
C. If you come into contact with a dead body.
D. If you walk through a grave yard.
E. If you are healed of a disease.
F. After you deliver a baby.
G. If you touch someone else who is ceremonially unclean.
H. If you show excessive anger.
2. Secondly, we are to immerse ourselves as an act of repentance.
3. Third, we are to immerse ourselves whenever we profess a life-changing commitment.
4. Fourth, we are to immerse ourselves whenever we receive special spiritual revelation.
5. And fifth, we are to immerse ourselves as an act of thanksgiving. (Notice that # 2-5 all relate to the mikvah unto salvation.)
As you can see, the manner by which Yohanan the Immerser (John the Baptist) “immersed” Yahshua, our Messiah was totally different from the traditional baptism method used by Protestants today.
