Who is the Holy Spirit?
Quick answer
The Holy Spirit is God — the third person of the Trinity — who lives in believers, helps them understand Scripture, convicts of sin, and produces Christlike character. He is a person, not a force.
The Bible speaks of the Spirit as personal: he teaches, guides, comforts, and can be grieved. He is fully God, alongside the Father and the Son.
Jesus promised the Spirit as a “Helper” who would be with his followers. At conversion, the Spirit comes to live in a believer, beginning a lifelong work of transformation.
The Spirit produces “fruit” — love, joy, peace, patience, and more (Galatians 5:22–23) — growing believers into the likeness of Jesus.
