God's Spirit is not a seperate person!
God is a Spirit says Christ in John4:24. And 1Cor2:11 makes clear that Gods Spirit is God's Own Spirit. Also we know God sent 7 Spirits to Earth as you read in Revelation 5:6, yet "God is One", says Romans3:30.
Most people however cannot fathom how God can be in Heaven, but can also work and be on Earth. God works through His Own Spirit of which 7 are poured out over the Earth. But aren't those seperate persons then? No, because God is One; and "God is a Spirit" (John4:24).
If I would lift a pillow from a footstool no one would say my arm is a seperate person, neither that my other arm would be a person. Both arms belong to my body as a whole.
In the same way God who is a Spirit works through 7 Spirits on His Footstool (Earth). His Spirits are His Own as He is a Spirit and He is One .
"Heaven is My Throne, and Earth is My Footstool... says the LORD", Acts7:49.
Christ however has a risen body says Romans10:9 and Romans 8:11. And he now sits at the right side of God says Mark16:19 as God's HighPriest says Hebrews8:1-2. God YHWH isnot His Own HighPriest!
"if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved", Romans10:9
"If the Spirit of Him Who raised Jesus from the dead dwells in you, He Who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit Who dwells in you.", Romans8:11
Eternal life when you believe in 1 true God and in 1 Lord Christ, John17:3+John 14:1. Only saved when believe in 1 Lord Christ and in 1 God that raised Christ back to life, Romans10:9.
"So then the Lord Jesus, after he had spoken to them, was taken up into heaven and sat down at the right hand of God", Mark 16:19
"Now the point in what we are saying is this: we have such a High Priest, one who is seated at the right hand of the throne of the Majesty in heaven, a minister in the holy places, in the true tent that the LORD set up, not man", Hebrews8:1-2
Are you saved? Will you get life eternal? Christ is clear about what is needed to get life eternal in John17:3 which can therefore be called the true Gospel: "This is life eternal: that they know Thee, the One True God, and Jesus Christ whom Thou has sent".
Knowing also means believing in them as Christ states in by directly saying: "Believe in God, also believe in me".
Of course that knowledge and faith has to be established accordingly:
1. Baptism by immersion leading to Christ, Acts19:5, Galatians 3:27 followed by:
2. Prayer with the laying on of hands leading to God and receipt of the Spiritual Gifts, Acts19:6, Acts8:17-18.
