As Christians, we embrace a historic formula about God’s being. We say, “God is One in essence and three in person.” In other words, God is triune; He is a Trinity. This means there are three persons within the Godhead.

The differences among the three, the Father, Son, and Holy Spirit, are real differences but not essential differences. In other words, there is only one essence to the Godhead, not three.

In our experience as human beings, each person we meet is a separate being. One person means one being, and vice versa. But in the Godhead, there is one being with three persons. We must maintain this distinction lest we slip into a form of polytheism, seeing the three persons of the Godhead as three beings who are three separate gods.

The fact that the Holy Spirit is a person is seen in a multitude of ways in Scripture. One of the primary evidences is that the Bible repeatedly and consistently uses personal pronouns to refer to Him. He is called “He,” “Him,” and so on.

His personality is proved: From the fact that the attributes of personality, as intelligence and volition, are ascribed to him (John 14:17, 26; 15:26; 1 Cor. 2:10, 11; 12:11). He reproves, helps, glorifies, intercedes (John 16:7–13; Rom. 8:26)

The Hebrew word for Spirit (Hebrew ruah, Greek pneuma) is the word breath. The meaning of these words is simply not a force, power or energy. But life!

In Creation:

Genesis 1:2 The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters. 3 Then God said, “Let there be light”; and there was light.

Genesis 2:7 And the Lord God formed man of the dust of the ground and breathed into his nostrils the breath of life; and man became a living being.

Job 33:4 The Spirit of God has made me, And the breath of the Almighty gives me life.

Birth of Jesus:

Matthew 1:18 Now the birth of Jesus Christ was as follows: After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit.

Luke 1:35 And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.

Matthew 1:20 But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit.

Resurrection of Jesus:

1 Peter 3:18–19 For Christ also suffered once for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh but made alive by the Spirit, 19 by whom also He went and preached to the spirits in prison

The Holy Spirit gives new life:

Ezekiel 36:26–28 I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh. 27 I will put My Spirit within you and cause you to walk in My statutes, and you will keep My judgments and do them. 28 Then you shall dwell in the land that I gave to your fathers; you shall be My people, and I will be your God.

Ezekiel 37:1–14

1 The hand of the Lord came upon me and brought me out in the Spirit of the Lord, and set me down in the midst of the valley; and it was full of bones. 2 Then He caused me to pass by them all around, and behold, there were very many in the open valley; and indeed they were very dry. 3 And He said to me, “Son of man, can these bones live?” So I answered, “O Lord God, You know.” 4 Again He said to me, “Prophesy to these bones, and say to them, ‘O dry bones, hear the word of the Lord! 5 Thus says the Lord God to these bones: “Surely I will cause breath to enter into you, and you shall live. 6 I will put sinews on you and bring flesh upon you, cover you with skin and put breath in you; and you shall live. Then you shall know that I am the Lord.” ’ ” 7 So I prophesied as I was commanded; and as I prophesied, there was a noise, and suddenly a rattling; and the bones came together, bone to bone. 8 Indeed, as I looked, the sinews and the flesh came upon them, and the skin covered them over; but there was no breath in them. 9 Also He said to me, “Prophesy to the breath, prophesy, son of man, and say to the breath, ‘Thus says the Lord God: “Come from the four winds, O breath, and breathe on these slain, that they may live.” ’ ” 10 So I prophesied as He commanded me, and breath came into them, and they lived, and stood upon their feet, an exceedingly great army. 11 Then He said to me, “Son of man, these bones are the whole house of Israel. They indeed say, ‘Our bones are dry, our hope is lost, and we ourselves are cut off!’ 12 Therefore prophesy and say to them, ‘Thus says the Lord God: “Behold, O My people, I will open your graves and cause you to come up from your graves, and bring you into the land of Israel. 13 Then you shall know that I am the Lord, when I have opened your graves, O My people, and brought you up from your graves. 14 I will put My Spirit in you, and you shall live, and I will place you in your own land. Then you shall know that I, the Lord, have spoken it and performed it,” says the Lord.’ ”

Spirit is the living waters:

John 7:37 On the last day, that great day of the feast, Jesus stood and cried out, saying, “If anyone thirsts, let him come to Me and drink. 38 He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.” 39 But this He spoke concerning the Spirit, whom those believing in Him would receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified.

Isaiah 44:3 For I will pour water on him who is thirsty, And floods on the dry ground; I will pour My Spirit on your descendants, And My blessing on your offspring; 4 They will spring up among the grass Like willows by the watercourses.’

Titus 3:4 But when the kindness and the love of God our Savior toward man appeared, 5 not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, 6 whom He poured out on us abundantly through Jesus Christ our Savior, 7 that having been justified by His grace we should become heirs according to the hope of eternal life.

Ephesians 2:1–6  And you He made alive, who were dead in trespasses and sins, 2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, 3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others. 4 But God, who is rich in mercy, because of His great love with which He loved us, 5 even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), 6 and raised us up together, and made us sit together in the heavenly places in Christ Jesus.

The Spirit sets believers free from bondage to works that lead to death:

Romans 8:2 For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death.

Romans 8:6 For to be carnally minded is death, but to be spiritually minded is life and peace.

Romans 8:14 For as many as are led by the Spirit of God, these are sons of God.

Galatians 6:8 For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life.
