I disagree with the first two posters. They have a point- To be baptized is to publicly
acknowledge one's faith in Christ as Savior and Lord by being immersed in water
(or in some instances, by having water placed on the head). Since acceptance with
God is based solely on trust in the person of Christ who died for our sins and rose
from the dead, water baptism is only a sign or outward indication of one's faith. It is
not necessary for salvation. This is only one definition of baptism- the one definition
that religious organizations would use.
Another definition is- a Christian sacrament (formal religious ceremony)signifying
spiritual cleansing and rebirth. The ceremony could be just for oneself. Baptism
represents, and visually depicts, the washing away of all sin by Christ.
It does NOT -as a ritual and in itself- redeem anyone. But is a "promise" of salvation
to "as many as the Lord our God will call to Himself.'
I did an un-dedication ceremony where I burned WT materials- representing my
invalidating my dedication to WTS. Nobody else was there, it was for me personally.
Do what you want, if it brings you what you need. Many religions (mostly non-Christian)
have personal ceremonies where you present yourself to God or perform some
rite of passage.
