The Holy Spirit is God — the third person of the Trinity — who convicts the world of sin (John 16:8), regenerates believers, indwells them, seals them, gifts them for service, and progressively makes them like Christ. Here’s a walkthrough of His work from conviction to glorification.
The work of the Holy Spirit is to manifest the active presence of God in the world and especially in the church. The Holy Spirit (1) empowers by giving life (John 6:63) and power for service (Acts 1:8). He also (2) purifies (1 Corinthians 6:11), (3) reveals (2 Peter 1:21), including guiding, directing, teaching, illuminating, and assuring (John 16:13), and (4) unifies.
Frequently Asked Questions
Is the Holy Spirit a person or a force?
A person — Scripture says He teaches (John 14:26), speaks (Acts 13:2), can be grieved (Ephesians 4:30), and can be lied to as God (Acts 5:3–4). Forces don’t grieve. He is the third person of the Trinity, fully God (Matthew 28:19).
What does the Holy Spirit do in a believer’s life?
He regenerates (Titus 3:5), indwells (1 Corinthians 6:19), seals as God’s guarantee (Ephesians 1:13–14), assures us we’re God’s children (Romans 8:16), empowers witness (Acts 1:8), distributes gifts (1 Corinthians 12:7–11), and grows His fruit — love, joy, peace, and the rest (Galatians 5:22–23).
How do I know if I have the Holy Spirit?
Every genuine believer has Him — “Anyone who does not have the Spirit of Christ does not belong to him” (Romans 8:9). The evidence isn’t dramatic experiences but direction: love for Christ, conviction over sin, growing fruit, and the inner witness crying “Abba! Father!” (Romans 8:15–16).
