...but there is only one Spirit.
So if the Father has His own Spirit, as you say, and if Jesus has his own Spirit, and the Holy Spirit is yet another Spirit---then that makes three Spirits not one.
Would you agree that we are...
(Mind/Spirit)
(Body)
(Soul)
... as Human beings?
Could you call your Soul your Spirit, or your Body your Soul? Could you call the Spirit the Body?
Could it be that we are made in HIS image, but His infinite Existence can do things, our created existence can't?
As in... All one, but God's "Body" (Memra/Logos/Son) can be in a Location, while God's (Spirit/Father/Mind) is literally EVERYWHERE.
Consider this... The Holy Spirit equates to the very (SOUL) of God. Thus... when Jesus says... I am in my Father and my Father is in Me... He is saying (My Father and I share the very same SOUL)...
Only ONE GOD! But... God's Soul... (The Holy Spirit)... Again is Divine and can indwell over a billion people at one time per (Ephesians 1:13) and yet, only the (SPIRIT - Gen. 1:2 and TRUTH - John 14:6) in light of ... (John 4:24; 1;1; 10:30; John 14:11)... Are referenced in (John 10:30) and are the ACTUAL PRESENCE of GOD...
God indwells us per, Romans 8:9, but that doesn't make us God, just because God's Holy Spirit (Soul) resides within us because of God's miraculous work of Creation and Salvation (Ephesians 2:8f)
What does this insanity mean? It means Jesus is AWESOME and Incomprehensible... yet He has provided His (Holy Spirit, that we might grasp a bit to come and Spiritually Comprehend a fraction of the infinite we will never fully understand after an infinity!
God's TriUne Being is uniqe to our TriUne being. In specific terms... God is Ultimately (Omnipotent, Omniscient and Omnipresent).
God is Disembodied and within Body at the Same time... (Examples... Ex. 33:18-23 and 1 Timothy 3:16)
That is Divine. You can't get hung up on simple human thinking... He is genuinely (TRI) and (UNE)
