...further establishing that the Persons of the Trinity are persons and not inanimate things: ...
Example: - In Mark 10:17 a man addresses Jesus' humanity, calling him
"Good teacher". Jesus replied, "Why do you call me good? No one is
good except God alone."
Interpretation: "There's no such thing as a good human being", because the man was approaching Jesus the man, the teacher.
The Holy Spirit can be resisted - [but how can we resist someone who has ultimate power?] Free will. God decided a long time ago that it would bring no glory to him if we were mere robots. So God gave us the free will so we can decide freely to worship him. But we also have the free will to resist the Holy Spirit.
Example: - Stephen was doing miracles, and attracting a crowd. Religious leaders decided they wanted to get rid of him, but Stephen told them off, outlining to them how Jesus was portrayed in the OT. "...you always resist the Holy Spirit. Acts 7:51.
Mystery: A dilemma exists within the understanding of the Holy Spirit regarding the "Blasphemy of the Holy Spirit" = the unforgivable sin. Seems to be akin to resisting the Holy Spirit, although there are instances of people resisting God, and resisting Jesus, without fatal consequences.
Matt 12.31 -- [Jesus] "Every sin and blasphemy will be forgiven men, but the blasphemy against the Holy Spirit will not be forgiven. ......"
So: Where does resist turn into blasphemy?
Jesus addresses this in Matthew 12:31-32. After casting out a demon, the teachers of the Law accused him of doing it by the power of Beelzebub, the Prince of Demons. After teaching them by parable that Satan cannot cast out Satan, he said to them, "And so I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Holy Spirit will not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age, or in the age to come. And then Mark adds, in Mark 3:30: "He said this because they were saying, 'He has an evil spirit.'"
On a brighter side, it is also possible to obey the Holy Spirit,
(again, indicating that he is a person, not an it).
Obeying is the smarter choice.
Example: Peter at Joppa, at the house of Simon the Tanner.
Cornelius sent for Peter, Peter had a dream (trance) -- saw in his vision a
sheet full of unclean animals. Three times.
Acts 10:19: The Spirit spoke to Peter, telling him he had three visitors. Peter obeyed and went down to greet them.
So the word "He" is used in Scripture to refer to the Holy Spirit.
But that's not the whole story. Maybe there is a hierarchy.
(complex, but don't let it get in your way).
At the last supper, Jesus was trying to help the disciples understand what was going to happen.
John 14:5 - [Thomas]: "We don't know where you're going... how can we know the way?"
John 14:8 - [Phillip]: "Show us the Father". [Jesus]: "Anyone who has seen me has seen the Father".
Generation: defined as the eternal relationship between the Father and the Son. (It does not denote that God Made or created the Son.) Not a matter of chronology. It is a matter of logic: the process set up for decision-making. Father-Son-Holy Spirit in that order does not imply chronological order, nor level of importance.
Also The Holy Spirit does not send the Son. The Father sends the Son.
John 1:14 -- "Sent by the Father". So the Father has a slightly different role from the other two.
Procession: The Holy Spirit can be sent by either the Father or the Son.
Acts 2:32 - Received from the Father the promised Holy Spirit.
John 3:34 - God sends the Spirit without limit.
John 15.26 - Jesus: "...[The Holy Spirit] whom I will send to you, from the Father".
John 21 - "As the Father sent me, so send I you." ... And he breathed on them, and they received the Holy Spirit.
Conclusion: The Father Sends the son.
