Who Is the Holy Spirit?

And Why the Church Can’t Function Without Him

The Holy Spirit is not a force. He is not a concept. He is not a feeling or a theological accessory added to the Christian life. The Holy Spirit is God. He is the third Person of the Trinity—eternal, holy, and active in every part of redemptive history. He is the life of the Church, and without Him, there is no Church.

Yet today, in many Christian circles, the Holy Spirit is either misunderstood, replaced with intellectual theology, or relegated to emotional experiences detached from biblical truth. In others, He is almost entirely ignored.

It was not so in the early Church.

The Spirit of God from the Beginning

“In the beginning… the Spirit of God was hovering over the face of the waters.”
— Genesis 1:2

From creation, the Holy Spirit was present—active, powerful, and creative. Throughout the Old Testament, He empowered judges, prophets, and kings. But the prophets spoke of a coming day when the Spirit would be poured out on all flesh—young and old, sons and daughters (Joel 2:28).

That day came at Pentecost.

The Spirit Given to the Church

“You will receive power when the Holy Spirit has come upon you, and you will be My witnesses…”
— Acts 1:8

The Church was born not in a strategy meeting, but in a prayer meeting—and with the arrival of the Spirit. Tongues of fire rested upon them. They spoke boldly. They preached with power. Thousands believed. The Holy Spirit did what no man could manufacture: He breathed life into the Body of Christ.

From that day forward:

• He filled believers with courage and joy
• He convicted hearts of sin and truth
• He guided decisions and planted churches
• He spoke through ordinary men and women
• He comforted the persecuted
• He led discipleship, mission, and unity

The Early Church’s Relationship with the Spirit

The early believers didn’t just believe in the Spirit—they depended on Him. They didn’t have seminaries, creeds, or commentaries—they had Scripture, prayer, and the indwelling presence of God.

They didn’t ask: “What do the theologians say?” They asked:

“What is the Spirit saying to the churches?”
— Revelation 2:7

When the Spirit Is Replaced

In later centuries, as the Church began to elevate hierarchy, tradition, and intellect, the living voice of the Spirit was increasingly replaced with systems. Doctrine was debated in councils, but personal reliance on the Spirit was often diminished.

This is still true today:

• Some treat the Spirit as a theological label, not a present Person.
• Others reduce Him to mystical encounters devoid of discernment.
• Still others ignore Him entirely in favor of academic clarity or church tradition.

But a church without the Holy Spirit is like a body without breath.

Who Is the Holy Spirit?

• He is God (Acts 5:3–4)
• He is a Person, not a force (John 14:16–17)
• He is the Spirit of Truth (John 16:13)
• He teaches, guides, convicts, comforts, speaks, and empowers
• He is the indwelling presence of Christ in the believer (Romans 8:9–11)

What We Can Learn

1. The Church cannot function without the Holy Spirit.
2. We must know Him as a Person, not an idea.
3. The Spirit leads us into truth, never apart from Scripture.
4. We are commanded to walk by the Spirit—not by flesh or intellect.
