You were baptized as a baby Must you now be re baptized as a 75 year old adult?
If you believe that the baptism of infants is valid then no.
If you believe that baptism is required as a testimony of the
new life a believer has started on following genuine repentance and
acceptance of Christ as Saviour then you will realize that the
sprinkling received as a baby was not in line with this
definition.Therefore you remain unbaptized and you wouldn't be
getting re- baptized.
Basically, you need to repent of your sins before they can be
removed by God. Infants cannot do this so you are unbaptized if you
"got wet" as an infant.
Further, the purpose of baptism is to place you in an obedient
position for God to remove your sins. Remember, Peter told us we
need to repent AND be baptized to remove our sins (Acts 2:38).
Unfortunately few teach this today.
And now why delay? Arise, and be baptized, and wash away your
sins, calling on the name of the Lord (Acts 22:16).
