It really doesn't though.
It does. The Father, Son, and Holy Spirit are repeatedly talked about as distinct persons. That Jesus is God is without question; that is the whole point of John 1:1-18. Yet, he isn’t the Father or the Holy Spirit and the Father isn’t the Holy Spirit. And, we know there is only one God.
It is the Spirit of GOD that is GOD, as GOD is spirit and GOD is one, all encompassing, all knowing, all powerful GOD.
Yes, the Holy Spirit is God, but so is the Father and the Son.
There is One Spirit. It is this same Holy Spirit of GOD that Jesus was anointed with.
There is one Holy Spirit that came to rest on Jesus at his baptism, at which time the Father spoke from heaven. Three persons, one God.
It is the Spirit of GOD that is Christ.
The Christ is the Son, not the Holy Spirit. Jesus certainly didn't think he was the Holy Spirit, seeing himself as quite distinct from him:
Luk 24:49 And behold, I am sending the promise of my Father upon you. But stay in the city until you are clothed with power from on high.” (ESV)
What is that promise that Jesus is sending?
Joh 14:16 And I will ask the Father, and he will give you
another Helper, to be with you forever,
Joh 14:17 even
the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you. (ESV)
Joh 15:26 “But when
the Helper comes,
whom I will send to you from the Father,
the Spirit of truth,
who proceeds from the Father,
he will bear witness about me. (ESV)
Joh 16:7 Nevertheless, I tell you the truth: i
t is to your advantage that I go away, for if
I do not go away, the Helper will not come to you. But if I go, I will send him to you.
Joh 16:8 And when
he comes,
he will convict the world concerning sin and righteousness and judgment:
Joh 16:9 concerning sin, because they do not believe in me;
Joh 16:10 concerning righteousness, because
I go to the Father, and you will see me no longer;
Joh 16:11 concerning judgment, because the ruler of this world is judged.
Joh 16:12 “I still have many things to say to you, but you cannot bear them now.
Joh 16:13 When the Spirit of truth comes,
he will guide you into all the truth, for
he will not speak on
his own authority, but
whatever he hears he will speak, and
he will declare to you the things that are to come.
Joh 16:14 He will glorify me, for
he will take what is mine and declare it to you.
Joh 16:15 All that the Father has is mine; therefore I said that
he will take what is
mine and declare it to you. (ESV)
The flesh profits nothing. Even today; what is it that makes up the body of Christ? Is it not believers as a whole that make up the boC? And is it not by what that body produces that we know of whom they belong?
What does any of this have to do with the Trinity?
GOD and Christ live in the believer.
God and Christ? That's two Gods for you.
There aren't three GODS living within the heart and mind of the believer. There is One Spirit.
There are three persons in the one God, one of them being the Holy Spirit, the primary one spoken of, actually, as that is his function in the life of the believer.
It is the very Spirit of GOD that fills the temple, making that vessel the Holy temple of GOD. A vessel devoid of contents is just an empty vessel.
Okay, but what does this have to do with the Trinity?
