Reading https://dovercoc.org/Sermons/HS.html may be very helpful in entering this discussion. The Holy Spirit is a person, a divine being. He is part of the Eloihim of Genesis1:1 and was the active ingredient in Genesis 1:2. The Holy Spirit in all 231 cases of mention in the Bible is always spoken of as "he," never "she" or "it." A search of the American Standard Bible shows that "Spirit," "Holy Spirit," "God's Spirit," or "My Spirit" (God speaking) occurs 231 times or in 2% of all mentionings of Diety in the scriptures. Additionally, Jesus speaks of the Holy Spirit as "the Comforter" is John 15: 26 and 16:7 and as "the Spirit Of Truth" in John 16: 13.

Some have difficulty in dealing with the Godhead in a Trinitarian way. How can "one God" be God the Father, God the Son, and God the Holy Spirit? Such an analysis becomes much easier when we remember that we as humans were created in the image of God (Genesis 1:26), "in Our image." Don't we as humans have three dimensions? We have physical bodies--pinch yourself and see if you don't feel it! Although this analogy isn't a perfect model, consider Jesus Christ, who was God in the flesh, as being like our physical bodies. Secondly, we have an intellectual component which accomplishes the executive and memory functions of the overall body, the mind or brain. The counterpart to that part of us is God the Father, the "Jehovah God" [MKJV choice of words especially] which made the decision to create man (Genesis 1: 26-31). And, thirdly, each of us as humans has a spirit. Without that spirit, we are dead (James 2: 26). It was the spirit that God breathed into make to make him a living soul (Genesis 2: 7). The spirit is the life force that is within us. An additional function of our spirit is our emotions, our attitudes and values. The Holy Spirit of God is the same counterpart.

The three parts of the Godhead know what each other is doing, and cooperate and coordinate in everything. See John 16: 5 through 16 to get the flavor of the Divine Unity. To have three separate spirits that operated without the collaboration of each other would be to have a universe in chaos.

As alluded to above and in https://dovercoc.org/Sermons/HS.html , we know the least about the Holy Spirit compared to God the Father and God the Son. The Godhead has its reasons for this, not all of which are made expressly known to us as mankind. But think about it, in our human nature, isn't it our character to reveal the emotional parts of ourself last as we get to know people? Hasn't experience taught us that it may not be wise to open our hearts up and "bare our souls" to anybody or anyone who comes along? The Spirit of God has had His hurts also. In the days of Noah, man became so wicked, and so unmindful of God, that it grieved the very Spirit of God to see what was going on (Genesis 6: 3, 6). Israel provoked God so much in the unrepentant idolatry that He gave up on the Hebrew nation as being His people (2 King chapter 17). God opened the doors to Jews and Gentiles alike to find a remnant that would serve Him (Romans chapter 11).

None of us as humans like to have our emotions trifled with. We don't like being lied to or mislead. We don't like "fair weather friends." God's Spirit is exactly the same way. We're like He is in that regard. Jesus reminded Satan "Thou shalt not tempt the Lord thy God" (Matthew 4: 7).

Functionally, there is some degree of division of labor among the Godhead. A close reading of John 16: 7-16 reveals that the Holy Spirit could not come to accomplish His job of comforting until Jesus had fulfilled His mission and had returned to the Father. We don't know why that restriction existed. Some day, if we think it still matters, we can ask Him.

Part of the Holy Spirit's mission was to convict men of sin, the sin they knew that was in their hearts, in order to lead them to repentance. We see that exact mission being fulfilled on the day of Pentecost in Acts 2: 37. Another part of the Holy Spirit's mission was to communicate the word of God to the men who wrote down the Scriptures (2 Peter 1: 21). This is how the word of God was "God breathed" or inspired (2 Timothy 3: 16, 17). In our modern time, the Holy Spirit will never say or do anything that contradicts the Scriptures, the faith that was once for all delivered to the saints (Jude 3; Galatians 1: 8, 9; Revelation 22: 18, 19).

The Holy Spirit works in translating our prayers into utterances that can be brought before the Father's throne (Romans 8: 26, 27). He searches our hearts, our emotions, to bring those requests and observations to Jehovah. Without the Spirit's intercession, our prayers would be useless. Without having asked through the Son, our prayers would not be heard (John 14: 14; 16: 23).

The Holy Spirit has always worked somewhat behind the scenes, though many times in very powerful ways. And try this on for size: drawing near to the Holy Spirit occurs somewhat indirectly, as a result of drawing near to God through His Son, Jesus Christ. Don't try to cut the Son out of the deal as you try to draw near to God. John 14: 1-6 says that such a strategy will be futile.
