The short answer to this question is, yes, the Holy Spirit as described in the Bible is fully God. Along with God the Father and God the Son (Jesus Christ), God the Spirit is the third member of the Godhead or the Trinity.
Those who challenge the idea that the Holy Spirit is God suggest that the Holy Spirit may simply be an impersonal force of some kind, a source of power controlled by God but not fully a person Himself. Others suggest that perhaps the Holy Spirit is just another name for Jesus, in spirit form, apart from His body.
These ideas do not line up with what the Bible actually says about the Holy Spirit, though. The Bible describes the Holy Spirit as a person who has been present with the Father and the Son since before time began. The Spirit is integral to all of the things that God is described as doing in the Bible.
The Spirit of God was present at and involved in creation (Genesis 1:2; Psalm 33:6). The Holy Spirit moved the prophets of God with the words of God (2 Peter 1:21). The bodies of those in Christ are described as temples of God because the Holy Spirit is in us (1 Corinthians 6:19). Jesus was clear that to be “born again,” to become a Christian, one must be born “of the Spirit” (John 3:5).
One of the most convincing statements in the Bible about the Holy Spirit being God is found in Acts 5. When Ananias lied about the price of a piece of property, Peter said that Satan had filled Ananias’s heart to “lie to the Holy Spirit” (Acts 5:3) and concluded by saying that Ananias had “lied to God” (verse 4). Peter reveals that the Holy Spirit is God. Lying to the Holy Spirit is lying to God.
Jesus told His disciples that the Holy Spirit, the Helper, was different from Himself. The Father would send the Helper, the Spirit of truth, after Christ departed. The Spirit would speak through the disciples about Jesus (John 14:25–26; 15:26–27; 16:7–15). All three Persons Jesus mentions—Father, Son, and Holy Spirit—are God while being distinct from each other within the Trinity.
The three members of the Trinity show up, together yet distinct, at Jesus’ baptism. As Jesus comes up from the water, the Spirit descends on Him like a dove while the voice of the Father is heard from heaven saying that He is pleased with His beloved Son (Mark 1:10–11).
Finally, the Bible describes the Holy Spirit as a person, not a mere force. He can be grieved (Ephesians 4:30). He has a will (1 Corinthians 12:4-7). He uses His mind to search the deep things of God (1 Corinthians 2:10). And He has fellowship with believers (2 Corinthians 13:14). Clearly, the Spirit is a person, just as the Father and the Son are persons.
Indeed, the Bible is unequivocal that the Holy Spirit is, in fact, God, just as Jesus Christ and the Father are God.
No! The Holy Spirit is not a separate God, and also isn't a God next Jesus Christ and His Father.
If the Holy Spirit is a God, then we don't find any records that He has spoken to God Jehovah or Jesus Christ or both?
Does it have a mouth? Where in the Bible we can read "god holy spirit"? We want chapters and verses!!
I have ask this question about thousand of times, but still silence, and you are keeping pretending that you have the truth.
The truth is what is written in the Bible, not plucking verses here and there and making a false doctrine of what is written in the Bible. The Bible doesn't need no one to interpret for it. Because it interpreted itself, and you can read it also by others writer from the Bible.
I know Bible teaches that a FEW entered God's kingdom. And those FEW are these persons.
Revelation 12:17, and Revelation 14:12. And also those that have died searching for the truth. Or be killed by accepting Jesus Christ as their Lord and Saviour. But not those Trinitarians that knows that their teachings is false, and keep young people in mind out of the truth.
All Sunday keepers and all day keepers are from Satan. Go read just the little that I have wrote about the Sabbath day.
The title of this thread is missing a very important word Pipiripi because it says and asks - 'Is the Holy Spirit God' but it should ask 'Is the Holy Spirit Of YHWH' then YES it is Father YHWH Holy Spirit from Him!!! How do we know that for sure? Well because the GOOD OLD >>>RELIABLE<<<BIBLE TELLS US SO!
Genesis 1:2 - 'And the earth was without form, and void; and darkness was upon the face of the deep. And >>>the Spirit OF YHWH<<< (not another CREATOR!) moved upon the face of the waters.'
Why is it that MOST every single translation says the Holy Spirit is OF Father YHWH or just flat out YHWH's Spirit of Himself? Once again refuting false doctrine that Father YHWH Holy Spirit is somehow another 'god' and or 'person'??? Lets look at some translations below that exposes this false teaching ERROR of another 'god' and or 'person'!
Genesis 1:2 (ASV)- 'And the earth was waste and void; and darkness was upon the face of the deep: and the >>>Spirit of God<<< moved upon the face of the waters.'
Genesis 1:2 (CSB)- 'Now the earth was formless and empty, darkness covered the surface of the watery depths, and the >>>Spirit of God<<< was hovering over the surface of the waters.'
Genesis 1:2 (CJB)- 'The earth was unformed and void, darkness was on the face of the deep, and the >>>Spirit of God<<< hovered over the surface of the water.'
Genesis 1:2 (EXB)- 'the earth was completely empty. There was nothing on the earth. Darkness covered the ocean, and >>>God’s Spirit<<< moved over the water.'
Genesis 1:2 (GNV)- 'And the earth was without form and void, and darkness was upon the deep, and the >>>Spirit of God<<< moved upon the waters.'
Genesis 1:2 (TLB)- 'the earth was a shapeless, chaotic mass,* with the >>>Spirit of God<<< brooding over the dark vapors.*'
And you know something interesting of what is said in some translations , that say this below -
Genesis 1:2 (CEB)- 'the earth was without shape or form, it was dark over the deep sea, and God’s wind swept over the waters—'
Genesis 1:2 (EXB)- 'The [or…the] earth ·had no form and was empty [or was a formless void]. Darkness covered the ·ocean [deep], and ·God’s Spirit [or a mighty wind] was ·moving [hovering] over the water.'
So much for false teachings CULT 'churches' teaching the Spirit of Father YHWH is another 'god' and or 'person' because here it says above in those two translations that YHWH's Spirit is like a 'mighty wind', a 'wind' that 'swept' over the DEEP waters before CREATION WEEK BEGAN (of course CREATION WEEK ending on His HOLY, SANCTIFIED and RESTFUL 7th Day Sabbath!!!) AMEN!!!
'No teddy, the Holy Spirit is not God the Father!' says littledavid!
But what did the Bible just say in Genesis 1:2 (EXB)- 'the earth was completely empty. There was nothing on the earth. Darkness covered the ocean, and >>>God’s Spirit<<< moved over the water.'!!!
Obviously the Father's set apart Spirit is >>>OF<<< Him because its 'YHWH's Spirit' (EXB) and the Spirit >>>OF<<< Father YHWH is not >>>THE<<< Father but >>>FROM<<< or >>>OF<<< the Father!
Finally littledavidsays - God the Father and God the Holy Spirit are 2 separate persons'???
Then this 'person' that you are taking about has to have permission to function FROM THE FATHER and not only that but is a VERY WINDY 'creator' according to you littledavid???
Case in point by two witnesses below!
Genesis 1:2 (CEB)- 'the earth was without shape or form, it was dark over the deep sea, and God’s wind swept over the waters—'
Genesis 1:2 (EXB)- 'The [or…the] earth ·had no form and was empty [or was a formless void]. Darkness covered the ·ocean [deep], and ·God’s Spirit [or a mighty wind] was ·moving [hovering] over the water.'
Its always a good thing to refute your false teachings littledavid among all viewing! Your welcome!
How do we know that for sure? 
Well because the GOOD OLD >>>RELIABLE<<<BIBLE TELLS US SO!
