The Holy Spirit is a Person, NOT an impersonal active force like electricity:
John 14:16-18 (NASB): "I will ask the Father, and He will give you another Helper, that He may be with you forever; [that is] the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, [but] you know Him because He abides with you and will be in you.
Jesus taught that the Holy Spirit was another Helper (or Advocate) who was coming after Him. The Greek word for "another" in John 14:16-18 means "another of the same." So Jesus was saying that the Spirit would be another Helper just like Himself, in other words, the Spirit would be (1) a Person and (2) fully God in Nature.
And notice, the Spirit cannot be Jesus because the Spirit is "another" Person besides Jesus, and the Spirit cannot be The Father because The Father is sending the Spirit. Therefore, the only conclusion I arrive at from these verses is that the Holy Spirit is a THIRD Person who is fully God in Nature.
John 14:26 (NASB): "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.
The Spirit teaches people.
John 15:26 (NASB): "When the Helper comes, whom I will send to you from the Father, [that is] the Spirit of truth who proceeds from the Father, He will testify about Me,
The Spirit is a different Person than The Father, however, the Spirit does "proceed" from The Father. Notice also that the Spirit testifies about Jesus, who is a different Person. Both Jesus and The Father send the Spirit.
John 16:7-15 (NASB):"But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you. "And He, when He comes, will convict the world concerning sin and righteousness and judgment; [...] when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. "He will glorify Me, for He will take of Mine and will disclose [it] to you. "All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose [it] to you.
Jesus repeatedly referred to the Spirit as "He" and "Him," and said that He would do things that only a person can do, such as teach, speak, have an initiative, hear things, and take things from Jesus.
Romans 8:26-27 (NASB): In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for [us] with groanings too deep for words; and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to [the will of] God.
Here, the Spirit is described as having a mind, and praying to God for us, and interceding and groaning for us to God the Father. The Spirit is obviously a Person. An impersonal active force cannot have a mind and pray and intercede for us.
Acts 8:29 (NASB): Then the Spirit said to Philip, "Go up and join this chariot."
Here, the Spirit is speaking to Philip, giving him a command. How can an impersonal force speak and give a command?
Acts 10:19-20 (NASB): While Peter was reflecting on the vision, the Spirit said to him, "Behold, three men are looking for you. "But get up, go downstairs and accompany them without misgivings, for I have sent them Myself."
Now the Spirit speaks to Peter and tells him that He Himself has sent these men to find Peter. This Spirit does not sound at all like an impersonal active force like electricity.
Acts 13:2 (NASB): While they were ministering to the Lord and fasting, the Holy Spirit said, "Set apart for Me Barnabas and Saul for the work to which I have called them."
The Spirit chooses and calls the people that He desires to serve Him in special ways. The Spirit set apart for Himself Paul and Barnabas for special ministry work. How could the Spirit do this if He is not a person?
Acts 15:28 (NASB): "For it seemed good to the Holy Spirit and to us to lay upon you no greater burden than these essentials
Things can seem good or bad to the Spirit. The Spirit cannot be an impersonal force because the Spirit has feelings and desires and thoughts.
1 Corinthians 12:4-11 (NASB): Now there are varieties of gifts, but the same Spirit. And there are varieties of ministries, and the same Lord. There are varieties of effects, but the same God who works all things in all [persons.] But to each one is given the manifestation of the Spirit for the common good. For to one is given the word of wisdom through the Spirit, and to another the word of knowledge according to the same Spirit; to another faith by the same Spirit, and to another gifts of healing by the one Spirit, and to another the effecting of miracles, and to another prophecy, and to another the distinguishing of spirits, to another [various] kinds of tongues, and to another the interpretation of tongues. But one and the same Spirit works all these things, distributing to each one individually just as He wills.
Here the Spirit and the Lord [Jesus] and God the Father are declared to be working together in unity but are different Persons. It also says clearly that the Spirit has His own will and He distributes His gifts to whomever He chooses according to His own will. Definitely not an impersonal active force.
Ephesians 4:30 (NASB): Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
The Holy Spirit can be grieved (or feel hurt, feel pain). This is something only a person can do.
In the Scriptures, The Holy Spirit is always placed on an equal level with God the Father and Jesus Christ, but is always shown to be a different Person:
Matthew 28:19 (NASB): "Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit,
Notice that the "Name" of all Three is singular. They all have One Name (whether that "Name" is an actual name or is referring to their authority or reputation is debatable. It is possibly referring to both.)
And if the Spirit is simply God's active force, why would Jesus elevate it to the same level as His Father and Himself, and also, why would we be baptized in the Name of an impersonal force like electricity?
Matthew 12:31 (NASB): "Therefore I say to you, any sin and blasphemy shall be forgiven people, but blasphemy against the Spirit shall not be forgiven.
Luke 12:10 (NASB): "And everyone who speaks a word against the Son of Man, it will be forgiven him; but he who blasphemes against the Holy Spirit, it will not be forgiven him.
Jesus shows that blasphemy against Him can be forgiven, but not blasphemy against The Holy Spirit. How can you blaspheme the Spirit unless the Spirit is a Person? And why is blaspheming Him more serious than blaspheming Jesus?
Acts 5:3-4 (NASB): But Peter said, "Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back [some] of the price of the land? [...] You have not lied to men but to God."
How can you lie to an impersonal force like electricity? Also, notice how Peter says "You have lied to the Holy Spirit... you have lied to God." Peter equates the Holy Spirit with God.
Romans 15:30 (NASB): Now I urge you, brethren, by our Lord Jesus Christ and by the love of the Spirit, to strive together with me in your prayers to God for me,
Here Paul mentions the Three Persons together on an equal level, and also shows that The Holy Spirit has love, which is something only a person can have.
2 Corinthians 3:17-18 (NASB): Now the Lord is the Spirit, and where the Spirit of the Lord is, [there] is liberty. But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as from the Lord, the Spirit.
This is a very clear, explicit statement that the Holy Spirit is the Lord. Therefore, the Spirit is NOT an impersonal active force like electricity. Instead, Paul said that The Spirit is THE LORD! (Or, in the New World Translation, it says the Spirit is JEHOVAH)
2 Corinthians 13:14 (NASB): The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit, be with you all.
Once again, Paul places the Three Persons on an equal level, and this time he says that the Spirit has fellowship with us Christians. An impersonal force cannot have fellowship with human beings, can it?
Ephesians 4:4-6 (NASB): [There is] one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all.
Here Paul says that there is One Spirit, One Lord [Jesus], and One God [The Father]. Thus there are Three different Persons who are united as we worship and serve Them.
1 Peter 1:2 (NASB): according to the foreknowledge of God the Father, by the sanctifying work of the Spirit, to obey Jesus Christ and be sprinkled with His blood: May grace and peace be yours in the fullest measure.
And finally, Peter also shows here that The Three Persons are different, but work together in unity as we serve and worship Them.
Let me ask a couple final questions here:
Why do you believe that God the Father is a Person instead of an impersonal force? What would happen if you applied the same exact standards and tests to the Holy Spirit to see if the Spirit is a Person?
Why do you believe that Satan the Devil is a person instead of an impersonal force? What would happen if you applied the same exact standards and tests to the Holy Spirit to see if the Spirit is a Person?
