Questions About the Holy Spirit

Transformational knowledge of the Holy Spirit is understanding that can deepen your daily walk with the Lord. In this blog series, we’re exploring important questions about the Holy Spirit: How do you Receive the Holy Spirit, Is the Holy Spirit God, What Does the Holy Spirit Do, and What Are the Fruits of the Holy Spirit. These are crucial questions that can further your understanding of God, enrich your Christian faith, and empower your walk.

What does the Holy Spirit do?

The Holy Spirit does (at least) seven things in and for our salvation. The work of the Holy Spirit is the means by which all that Christ accomplished comes to benefit believers. From first conviction to final assurance, the Holy Spirit is the active agent who exposes our sin, gives us new birth, unites us to Christ, displays His glory, makes us holy, empowers us for service, and seals us forever—every step of salvation is His personal work. The Spirit is the unseen hand that sweeps the heart clean, awakens faith, grafts the soul into Christ, lifts Him high, fits the believer for service, and presses God’s own seal into the wax of our lives guaranteeing the promise until the Day of delivery.

A List of What the Holy Spirit Does

• He convicts—flashing light on hidden sin and summoning the world to repent.
• He converts—birthing us anew, planting love’s certainty that God is for us.
• He applies—knits us to Christ so every trophy of Calvary becomes our own.
• He glorifies—spotlights the Son, never Himself, making Jesus unmistakable.
• He sanctifies—re-creates us in Christ’s image, imparting God’s own moral beauty.
• He equips—distributes gifts, each one a tool to build the household of faith.
• He promises—presses the royal seal upon the heart: authenticated, secured, loved forever.

What the Holy Spirit Does in More Depth

1. The Holy Spirit convicts.
The Holy Spirit acts like a giant searchlight, exposing the world’s wickedness, calling people to
repentance, and convicting the world of sin, righteousness, and judgment (John 16:8–11). The word “convict” is used in John 3:20 with the sense of bringing sins to light: “For everyone who does wicked
things hates the light and does not come to the light, lest his works should be exposed.”

2. The Holy Spirit regenerates.
Here are some of God’s promises about regeneration:
To all who welcome Jesus, He gives the right to become God’s children—born not of blood, or
human will, but of God himself. John 1:12–13

Whoever trusts the Son possesses eternal life; whoever rejects him remains under God’s wrath.
John 3:36

The Spirit alone gives life; the flesh achieves nothing. John 6:63–65

As Jesus famously told Nicodemus, “Unless one is born of water and the Spirit, he cannot enter the
kingdom of God” John 3:5

Titus 3:5 calls this work “the washing of regeneration and renewal of the Holy Spirit.”

There is no Christian life without the converting work of the Spirit. He enables us to understand and spiritually discern the things of God (1 Cor. 2:12–14). He grants us repentance that leads to life (Acts 11:18). He pours God’s love into our hearts so we can be assured that in Christ God is for us and not against us (Rom. 5:5).

3. The Holy Spirit applies.
The Holy Spirit is the bond, the glue by which Christ effectually unites us to Himself. This is the logic of Romans 8:9–11. If the Spirit of the risen Christ lives in you, you belong to Christ, your sin-dead body is already marked for future resurrection, and the same Spirit who raised Jesus is right now giving you his life so live like it. When we have the Spirit, we have Christ. And when we have Christ, we have the Spirit.

The Holy Spirit applies to the believer the benefits won by Christ, because the Holy Spirit is the Spirit of Christ.

4. The Holy Spirit glorifies.
The Holy Spirit will glorify me, Jesus told the disciples, “He will take what is mine and declare it to you” (John 16:14). The Holy Spirit speaks only what he hears (John 16:13). He declares what he is given (John 16:14b).

All three persons of the Trinity are fully God. The Son makes known the Father and the Spirit glorifies the Son. When we focus on Christ we give evidence of the Spirit’s work. We cannot worship Christ without the work of the Spirit. The work of the Holy Spirit is to bring glory to Christ by taking what is his teaching, the truth about his death and resurrection and making it known.

The Spirit is Jesus’ spotlight, not a rival stage-light. He never advertises Himself; He streams every ray onto Christ: His words, His cross, His resurrection. To fix our eyes on Jesus is proof the Spirit is working; to look anywhere else is to step out of the beam. Where the Spirit is active, Christ is center-stage.

5. The Holy Spirit sanctifies.
This is an important aspect of our salvation and walk in Christ. The Spirit gives the believer a new
position in Christ, set apart in Christ and sprinkled with His blood, and a new power in Christ (Eph. 3:16).

The Spirit works in us “for obedience to Jesus Christ” (1 Pet. 1:2). Peter elsewhere says that through
God’s precious and very great promises we may “become partakers of the divine nature” (2 Pet. 1:4).
The Spirit doesn’t just move you to a new seat; He gives you a new standing. In one moment He plants you in Christ—holy, blood-sprinkled, unbreakably secure—and in the next He pumps Christ’s own strength into your veins (Eph 3:16). Why? So that obedience stops feeling like duty and starts feeling like nature. Peter says God’s promises are invitations: “Come share My character.”

The point is that we can share in the qualities that are characteristic of God himself. Not deity—no one becomes the ocean, but the crystal-clear currents that flow from Him: love without envy, holiness without corrosion, joy without expiry. Every “yes” to those promises is another gulp of water that washes the salt of the old world off our skin.

6. The Holy Spirit equips.
By the work of the Spirit, believers are given gifts for ministry. Sometimes called “service” or
“activities,” the purpose of these gifts is to build up the Church. The manifestation of the Spirit is for the common good (1 Cor. 12:7) and the edification of the Church (1 Cor. 14:12, 26).

7. The Holy Spirit promises.
Ephesians 1:13–14 states that in Christ we “were sealed with the promised Holy Spirit, who is the
guarantee of our inheritance until we acquire possession of it.” A seal in the ancient world did three
things: it authenticated, it secured, and it marked ownership. All three elements are in view here. The seal of the Spirit authenticates us as true believers, secures our eternal safety, and marks us out as belonging to God.

This sealing is not a second blessing subsequent to salvation; it happens the moment when we become a Christian. The sealing at the end of Ephesians 1:13 is connected to hearing the word of truth and believing the gospel earlier in the verse. That’s when the sealing takes place. The sealing is a declarative fact, true of every Christian.

Subjectively, being sealed with the Spirit means we experience an inner authentication that we are indeed forgiven and loved by God. “The Spirit himself bears witness with our spirit that we are children of God” (Rom. 8:16). Or as Paul puts it earlier in Romans, “God’s love has
been poured into our hearts through the Holy Spirit” (Rom. 5:5). The Spirit assures us that we belong to God. Ideally, this assurance will be believed and felt.

Additional Scriptures Declaring What the Holy Spirit Does

The Holy Spirit is our teacher and guide, helping us understand God’s Word. He inspires scripture
and illuminates the truth.  John 14:26: “But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.”

The Holy Spirit intercedes for us, even when we don’t know how to pray. Romans 8:26: “In the same
way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit
Himself intercedes for us through wordless groans.”

The Holy Spirit empowers believers to resist sin and live righteously. Galatians 5:16: “So I say, walk by the Spirit, and you will not gratify the desires of the flesh.”

The Holy Spirit empowers us to witness. Acts 1:8 emphasizes the Spirit’s power to enable bold witness for Christ.

The Holy Spirit guides us. John 16:13 says, “But when He, the Spirit of truth, comes, He will guide you into all the truth.”

The Holy Spirit comforts us. Romans 8:16 assures, “The Spirit Himself testifies with our spirit that we are God’s children.”

The Holy Spirit sanctifies us. 2 Thessalonians 2:13 highlights the Spirit’s role in sanctification: “God chose you as first fruits to be saved through the sanctifying work of the Spirit and through belief in the truth.”

Why is all of this important?

By studying Bible verses about the Holy Spirit and inviting His work in our lives, we can grow in faith,
understanding, and power. The Holy Spirit is not just an abstract concept but a personal and transformative presence, drawing us closer to God and empowering us to live for His glory.
