Bible Verses About God, Jesus, and the Holy Spirit Being One
The question of how God the Father, Jesus Christ, and the Holy Spirit are one has been central to Christian faith for centuries. Known as the doctrine of the Trinity, this belief teaches that there is one God who exists in three distinct persons. While the word “Trinity” does not appear in the Bible, the concept is clearly woven throughout Scripture.
In this post, we’ll explore key Bible verses that reveal the unity of God, Jesus, and the Holy Spirit, and what this means for believers today.
Understanding the Trinity: One God in Three Persons
Before diving into specific verses, let’s clarify what Christians mean by the Trinity:
- One God — There is only one true God.
- Three Persons — The Father, the Son (Jesus), and the Holy Spirit.
- Equal in nature and essence — Not three gods, but one divine being.
The Bible consistently affirms monotheism while also revealing distinctions within the Godhead. Let’s look at how Scripture supports this truth.
1. The Oneness of God
The foundation of the Trinity is the belief that God is one.
Deuteronomy 6:4
“Hear, O Israel: The LORD our God is one LORD.”
This Old Testament declaration emphasizes that there is only one God. Christianity builds upon this truth — it does not contradict it.
Isaiah 45:5
“I am the LORD, and there is none else, there is no God beside me.”
The Bible repeatedly confirms there is no other God. Any understanding of Jesus and the Holy Spirit must align with this fundamental truth.
2. Jesus Is Fully God
The New Testament clearly declares that Jesus is not merely a prophet or teacher — He is divine.
John 1:1
“In the beginning was the Word, and the Word was with God, and the Word was God.”
This verse beautifully captures both distinction (“with God”) and unity (“was God”).
John 10:30
“I and my Father are one.”
Here, Jesus directly affirms His unity with the Father. His audience understood this as a claim to deity.
Colossians 2:9
“For in him dwelleth all the fulness of the Godhead bodily.”
Paul confirms that the fullness of God lives in Christ. Jesus is not partially God — He is fully divine.
3. The Holy Spirit Is Fully God
The Holy Spirit is not an impersonal force. Scripture reveals that He is divine and personal.
Acts 5:3–4
Peter tells Ananias he has lied to the Holy Spirit and then says, “thou hast not lied unto men, but unto God.”
Lying to the Holy Spirit is equated with lying to God — a clear affirmation of the Spirit’s deity.
2 Corinthians 3:17
“Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty.”
The Holy Spirit shares in the Lord’s identity and authority.
4. Father, Son, and Holy Spirit Together
Some of the clearest evidence of the Trinity appears when all three persons are mentioned together.
Matthew 28:19
“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.”
Notice the singular word “name”, not “names.” One name — three persons.
2 Corinthians 13:14
“The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all.”
Paul’s blessing reflects unity and equality among the three.
Jesus’ Baptism (Matthew 3:16–17)
- Jesus is baptized.
- The Holy Spirit descends like a dove.
- The Father speaks from heaven.
All three persons are present and active — distinct, yet united.
5. How Can Three Be One?
While the Trinity is a mystery beyond complete human understanding, Scripture gives us clarity:
- The Father is God.
- The Son is God.
- The Holy Spirit is God.
- There is only one God.
Rather than a contradiction, this reveals the depth of God’s nature. Christians don’t worship three gods. We worship one God in three persons, perfectly united in essence, purpose, and will.
Why the Trinity Matters for Believers
Understanding that God, Jesus, and the Holy Spirit are one isn’t just theological — it’s deeply personal.
Here’s why it matters:
- Salvation: The Father planned it, the Son accomplished it, and the Spirit applies it.
- Prayer: We pray to the Father, through the Son, in the power of the Holy Spirit.
- Relationship: God’s very nature is relational — love existed within the Trinity before creation.
The unity of the Trinity reveals a God who is powerful, present, and personal.
Final Thoughts: One God, Eternal and United
The Bible consistently teaches that God, Jesus, and the Holy Spirit are one. From Genesis to Revelation, we see a unified picture of one divine Being working through three distinct persons.
While human language struggles to fully explain this sacred mystery, Scripture leaves little doubt:
- There is only one God.
- The Father is God.
- Jesus is God.
- The Holy Spirit is God.
- They are eternally one.
For believers, this truth brings assurance, confidence, and awe. The God who created the universe is the same God who redeems, indwells, and sustains us — Father, Son, and Holy Spirit.
If you’re exploring the doctrine of the Trinity, start with these verses, meditate on them, and ask God for understanding. The more we study Scripture, the more clearly we see that our God is beautifully, powerfully, and eternally One.
