ever since I started attending a pentecostal church, here and there have always head of the preacher passing these two words to the congregation. @You are fill with the Holy spirit.
@the power of the Holy ghost will mount on you. So please my lovely brethren can contribut to topic by enlightening the world more about the Holy spirit and holy ghost or are they one.

Holy Spirit and Holy Ghost are the same.The words are used interchangeably.

They are not same.

Spirit is for the living, the immortal who never came into human form and had never experienced death while
Ghost is for the dead, saints who died before our existence.
The holy is an attribute for the pure in heart.

Holy Spirit (Judaism)
This article is about the term in Judaism.
For the Holy Spirit in Christianity, see Holy
Spirit (Christianity). For the Holy Spirit in
Islam, see Holy Spirit (Islam).
The Holy Spirit in Judaism generally refers
to the divine aspect of prophecy and
wisdom. It also refers to the divine force,
quality, and influence of God Most High
(Hebrew El Elyon) over the universe or over
God's creatures, in given contexts.[1]
The Hebrew language phrase ruach ha-
kodesh (Hebrew: רוח הקודש, "holy spirit" also transliterated ruaḥ ha-qodesh) is used in
the Hebrew Bible (Tanakh) and Jewish
writings to refer to the spirit of YHWH (רוח
יהוה). It literally means "the spirit of
holiness." The Hebrew terms ruacḥ
qodshekha, "thy holy spirit" (רוּחַ קָדְשְׁךָ), and
ruacḥ qodshō, "his holy spirit" (רוּחַ קָדְשׁ֑וֹ)
also occur. (When a possessive suffix is
added the definite article is dropped.)
Hebrew Bible
The term "ruacḥ haqodesh" does not occur
in the Tanakh, but occurs once in Psalm
51:11 and twice in the Book of Isaiah (Isaiah
63:10,11) with a possessive suffix. Those are the only three times that the phrase "holy spirit" is used in the Hebrew Scriptures, although ruach (רוח, literally "breath" or "wind" in various combinations with "God" is used often, and qodesh ("holiness" is also used often. Ruacḥ, much like the English word breath, can mean either wind or some invisible moving force ("spirit".
The first Hebrew Scripture use of the phrase ruacḥ haqodesh (but in a modified form as explained above) in Psalm 51 contains a triple parallelism:
10 "Create in me a clean heart, O God; and
renew a right spirit ( רוּחַ נָכֹון) within me."
11 "Cast me not away from thy presence;
and take not thy holy spirit ( רוּחַ קָדְשְׁךָ)
from me."
12 "Restore unto me the joy of thy
salvation; and uphold me with a ( רוּחַ נְדִיבָה)
free spirit."[2]
The other two times that the expression
occurs, in Isaiah 63 (R.V.), read:
10 "But they rebelled, and grieved his holy
spirit ( רוּחַ קָדְשׁ֑וֹ); therefore he turned to be
their enemy, and himself fought against
them."
11 "Then he remembered the days of old,
of Moses and his people, saying, Where is
he that brought them up out of the sea
with the shepherds of his flock? where is
he who put his holy spirit (רוּחַ קָדְשֽׁוֹ) in the
midst of them?"
Talmud
The term is discussed in the Babylonian
Talmud, Makkot 23b and elsewhere.
Rabbinical use is discussed by Joseph Jacobs and Ludwig Blau in the article "Holy Spirit"
in the Jewish Encyclopedia of 1911.[3]
In Judaism, God is One; the idea of God as a duality or trinity is considered shituf (or
"not purely monotheistic". The term ruacḥ
haQodesh is found frequently in Talmudic
and Midrashic literature. In some cases it
signifies prophetic inspiration, while in
others it is used as a hypostatization or a
metonym for God.[1] The rabbinical
understanding of the Holy Spirit has a
certain degree of personification, but it
remains, "a quality belonging to God, one of his attributes".[4]
In Rabbinic Judaism references to the spirit
of God abound, however apart from
Kabbalistic mysticism it has rejected any
idea of God as being either dualistic, tri-
personal, or ontologically complex.
Shekinah
The concept of shekhinah ("presence" is
also associated with the Holy Spirit in Jewish
tradition, such as in Yiddish song: Vel ich,
sh'chine tsu dir kummen "Will I, Shekinah,
to you come".[5]
