Who Is the Holy Spirit?

The Holy Spirit is God—the third person of the Trinity, fully and equally divine with the Father and the Son. Not an impersonal force, not merely God’s energy or a warm feeling, but a person who knows, wills, speaks, teaches, and can be grieved and lied to. When Ananias lied to the Spirit, Peter said he had lied “to God” (Acts 5:3-4)—the two are named as one. The Spirit is a “He,” not an “it.”

What is striking about the Spirit’s work is how self-effacing it is. Jesus said the Spirit would not speak of Himself but would take what belongs to Christ and make it known, glorifying the Son (John 16:13-14). The Spirit is not in the business of drawing attention to Himself; He is always pointing you to Jesus. So the surest sign of the Spirit’s presence is not a dramatic experience but a heart that trusts and confesses Christ—for “no one can say ‘Jesus is Lord’ except in the Holy Spirit” (1 Corinthians 12:3). If you believe in Christ at all, the Spirit has already done His work in you.

And how does He work? Here Lutherans are emphatic: ordinarily through means—the Gospel preached, the water of Baptism, the bread and wine of the Supper, the word of absolution. The Spirit is not floating loose, to be chased down through feelings or spiritual techniques. He has bound Himself to the Word and Sacraments, and there He reliably creates faith, forgives, comforts, and sanctifies. As Luther’s Catechism puts it, “the Holy Spirit has called me by the Gospel, enlightened me with his gifts, sanctified and kept me in the true faith.”

So the Spirit is not the vague, mysterious member of the Trinity you can safely ignore. He is God at work right now, quietly and powerfully, doing the one thing that matters most: bringing you to Christ and keeping you there.
