The Holy Spirit is God Himself, present with and in His people. Jesus promised "another Comforter, that he may abide with you for ever" (John 14:16), "Even the Spirit of truth" (John 14:17). At Pentecost "they were all filled with the Holy Ghost" (Acts 2:4). Today "The Spirit itself beareth witness with our spirit, that we are the children of God" (Romans 8:16).
Many Christians find the Holy Spirit the hardest person of the Trinity to picture. We can imagine a loving Father and we know Jesus from the Gospels, but the Spirit can feel vague. The Bible is not vague about Him. The Spirit moved over the waters at creation (Genesis 1:2), came upon Mary before the first Christmas (Luke 1:35) and filled the church at Pentecost. Jesus spoke of Him as a person who teaches, comforts and guides, not as an impersonal force. The King James Version usually says Holy Ghost, about ninety times; ghost is an old English word for spirit. It says Holy Spirit only a handful of times, including Psalm 51:11 and Ephesians 4:30. These twelve KJV verses introduce the Comforter Jesus promised, the day the Spirit was poured out, and what it means to live with God's Spirit inside you. For how the Father, Son and Spirit relate, see Bible verses about the Trinity, and for the Spirit's character in us, see Bible verses about the fruit of the Spirit.
The promised Comforter: who the Spirit is
1. John 14:16-17
"And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you."
On the night before the cross, Jesus promised His worried disciples another Comforter. The Greek word, parakletos, means someone called alongside to help: a helper, counselor or advocate. Another means one like Jesus Himself. This Comforter is the Spirit of truth, who dwelleth with you, and shall be in you. Jesus was about to leave them physically, but He would not leave them alone. As He said moments later, "I will not leave you comfortless: I will come to you" (John 14:18).
2. John 16:7
"Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you."
The disciples could not imagine anything better than having Jesus physically with them. Yet He said, It is expedient for you that I go away. Expedient means for your good. If Jesus did not go, the Comforter will not come unto you. While on earth, Jesus could be in only one place at a time. The Spirit can live in every believer everywhere at once. That is why Jesus could call His departure an advantage.
3. 1 Corinthians 2:10
"But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God."
Paul says God's wisdom is hidden from human pride but revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. Only God's own Spirit knows God fully, just as only your spirit knows your private thoughts (1 Corinthians 2:11). When you read Scripture and something suddenly makes sense, or a truth you knew in your head reaches your heart, that is the Spirit's work. Ask Him for understanding whenever you open the Bible.
4. Psalms 51:11
"Cast me not away from thy presence; and take not thy holy spirit from me."
David wrote Psalm 51 after the prophet Nathan confronted him about his sin with Bathsheba. In the middle of his confession he begged, Cast me not away from thy presence; and take not thy holy spirit from me. David had seen the Spirit leave King Saul (1 Samuel 16:14), and he dreaded losing God's presence more than anything. In Christ, believers are sealed with the Spirit (Ephesians 1:13), yet David's longing is a model: God's presence is the greatest treasure we have.
The Spirit poured out: Pentecost and new birth
5. Acts 2:2
"And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting."
Pentecost was a Jewish harvest festival, the Feast of Weeks, held fifty days after Passover, and Jerusalem was crowded with pilgrims. The disciples were praying together when suddenly there came a sound from heaven as of a rushing mighty wind. In both Hebrew and Greek, the word for spirit also means wind or breath. The sound filled the house, and flames like tongues of fire rested on each of them (Acts 2:3). God was announcing that the promised Spirit had come.
6. Acts 2:4
"And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."
they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. Visitors from many nations heard the disciples praising God in their own languages (Acts 2:8-11). It was the reverse of the tower of Babel, where languages divided people (Genesis 11:9). That day Peter preached and about three thousand people believed (Acts 2:41). Christians mark this day as Pentecost Sunday, often called the birthday of the church.
7. John 3:8
"The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."
Nicodemus, a respected teacher, came to Jesus at night, and Jesus told him he must be born again (John 3:3). Then He used a word picture: The wind bloweth where it listeth, that is, where it wishes. You cannot see the wind, but you can hear it and see what it moves. so is every one that is born of the Spirit. You may not be able to explain exactly how the Spirit changed your heart, but you can see the effects: new desires, new love, new life.
8. Ezekiel 36:27
"And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them."
Six centuries before Pentecost, God promised through Ezekiel, I will put my spirit within you, and cause you to walk in my statutes. The verse before promises a new heart in place of a heart of stone (Ezekiel 36:26). The law told people what to do but could not change their hearts. The Spirit does. Obeying God becomes something He works in us from the inside, not just a rule pressed on us from the outside.
Living with the Spirit today
9. Romans 8:16-17
"The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together."
Romans 8 is the great chapter on the Spirit, and these verses describe one of His sweetest works: The Spirit itself beareth witness with our spirit, that we are the children of God. He assures us that we belong. Children are heirs, heirs of God, and joint-heirs with Christ. The same passage says the Spirit helps us pray when we have no words (Romans 8:26). On days when you doubt God's love, the Spirit quietly reminds you: you are His child.
10. Ephesians 4:30
"And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption."
grieve not the holy Spirit of God. Only a person can be grieved; you cannot hurt the feelings of a force. The verse sits in a passage about speech and relationships, followed by a call to put away bitterness, and wrath, and anger (Ephesians 4:31). Harsh words and grudges sadden the Spirit who lives in us. Yet the same verse brings assurance: we are sealed unto the day of redemption. He grieves over our sin, but He does not abandon us.
11. 1 Thessalonians 5:19
"Quench not the Spirit."
Quench not the Spirit. To quench is to put out a fire. The Spirit is often pictured as fire (Acts 2:3), and Paul warns that we can dampen His work by ignoring His promptings, despising what He is doing in others, or holding on to known sin. The verses around it are full of joy, prayer and thanks (1 Thessalonians 5:16-18). Keeping the fire burning is less about dramatic moments and more about daily openness to God.
12. 1 John 4:13
"Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit."
How can you know that God lives in you? John answers, Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit. The context is love: If we love one another, God dwelleth in us (1 John 4:12). The Spirit's presence shows up in love for God and for other people. It is not measured only by feelings or spiritual experiences, but by a life that increasingly looks like Jesus.
A short prayer
Holy Spirit, thank You for coming to live in all who trust in Jesus. You are the Comforter He promised, the Spirit of truth. Open my eyes to understand God's Word. Assure me that I am God's child. Forgive me for the times I have grieved You with my words or quenched You by ignoring Your voice. Fill me again today. Produce Your fruit in me, and make my life look more like Jesus. In His name I pray, Amen.

Frequently asked questions
Who is the Holy Spirit?
The Holy Spirit is the third person of the Trinity, fully God along with the Father and the Son. Jesus speaks of Him as a person who teaches and reminds: "he shall teach you all things, and bring all things to your remembrance" (John 14:26). Christians are baptized "in the name of the Father, and of the Son, and of the Holy Ghost:" (Matthew 28:19). See Bible verses about the Trinity.
What does the Holy Spirit do?
He gives new birth (John 3:5), lives in believers, assures them they are God's children, helps them pray, guides them into truth and empowers them to witness. Jesus promised, "ye shall receive power, after that the Holy Ghost is come upon you" (Acts 1:8). He also produces character: "But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith," (Galatians 5:22). See Bible verses about gifts.
Why does the KJV say Holy Ghost instead of Holy Spirit?
In 1611, ghost was a normal English word for spirit, as in the German word Geist. The translators used Holy Ghost about ninety times and Holy Spirit only a few times, including "take not thy holy spirit from me" (Psalm 51:11) and "how much more shall your heavenly Father give the Holy Spirit to them that ask him?" (Luke 11:13). Both phrases refer to the same person.
How can I be filled with the Holy Spirit?
Paul commands, "be filled with the Spirit;" (Ephesians 5:18). Start by trusting Christ, then ask: Jesus said the Father will give the Holy Spirit to those who ask (Luke 11:13). Confess known sin, read Scripture, pray and stay close to other believers. Being filled is not a one-time event but a daily dependence on God. See Bible verses about revival.
