I have not seen anything in the bible or outside the bible that would cause me to be 100% sure of this . It is above my pay grade to say .
Bottom line would it make any difference to the way I serve and worship , no .
I believe the Holy Spirit is God's Spirit so yes , eternal , not the Son's Spirit , Jesus prayed the Father would give us another comforter . There are two Comforters as we can see in these verses .
John 14:16 Context
13And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
14If ye shall ask any thing in my name, I will do
it.
15If ye love me, keep my commandments.
16And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
18I will not leave you comfortless: I will come to you.
19Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
This .
I can't say I have ever worshipped the Holy Spirit . But yes I know the Holy Spirit is the comforter from experience more than once .
One night after an encounter on a forum online with a person that left me wondering if they were a person or a demon . I was sitting in my usual spot outside in the darkness to start my prayer time . I had been there a minute of two when I heard this awful wet snarl over my shoulder , it did not sound like any animal I have ever heard . But there was no fear on my part because
in the middle or right before the snarl the Holy Spirit said " That is demonic ." There was absolutely no normal fight or flight response or the hair standing up on the back of my neck . The demon could not touch me but they were NOT happy . Remember this verse .
Job 1:10 Hast not thou made an hedge about him, and about his house, and about all that he hath on every side? thou hast blessed the work of his hands, and his substance is increased in the land.
