The baptism of water, without the baptism of fire and the Holy Ghost attending it, is of no use; they are necessarily and inseparably connected. (TPJS p. 360), D&C 22:2
D&C
22:2
2 Wherefore, although a man should be baptized an hundred times it availeth him nothing, for you cannot enter in at the strait gate by the law of Moses, neither by your dead works.

Nephi 31:17-18
17 Wherefore,
do the things which I have
told you I have seen that your Lord and your Redeemer should do; for,
for this
cause have they been shown unto me, that ye might know the gate by
which ye
should enter. For the gate by
which ye
should enter is repentance and baptism by water; and
then cometh
a remission of your
sins by
fire and by the Holy Ghost.
18 And
then are ye in this strait and narrow path which
leads
to eternal life; yea, ye have entered
in
by the gate; ye have done according to the commandments of the Father and the Son; and ye have received the Holy Ghost, which
witnesses of
the Father and the Son, unto the fulfilling of the promise
which he
hath made, that if ye entered in by the way ye should receive.
