There are numerous teachings available on the Holy Spirit and it is not our intention here to present an exhaustive account of His nature, actions and character. What we want to look at are some practical ways of relating and cooperating with the Holy Spirit with the goal of knowing God.
The Holy Spirit is fully God. Though the word “Trinity” is not found in scriptures, there are definitely references to God as multi-parted. Though we continue to be curious about how God interrelates, we don’t wait for full understanding to accept the level of revelation God has given on this subject as “enough for now.” We know the Holy Spirit is a person, in that He has character, specific attributes, can speak for Himself, move, interact and has all other attributes of personality. So He can be grieved, pleased, patient, persistent, empowering, kind and expectant all at the same time.
As you pursue the knowledge of the Lord, you will experience the Holy Spirit Himself firsthand. For instance, when we speak of the manifestation of the Personal Presence of the Lord, I suspect it is the Holy Spirit that makes the Son and Father real to us on a personal level. What role each aspect of the Godhead plays is not clear, and probably varies, but I know that they “travel together.”
