Poinciana Christian Church - The Trinity Explained

Understanding the Trinity

God Is Truth
Many people agree that God is holy, loving, and truthful. The bigger question is:
Who is God?
Christians believe that the answer to this question matters because our understanding of God shapes everything else we believe.
The Bible teaches that there is one God who exists eternally as three distinct Persons—the Father, the Son, and the Holy Spirit. This doctrine is called the Trinity.
The word Trinity is not found in the Bible, but the doctrine is clearly taught throughout Scripture.

What is the Trinity?

What is the Trinity

The Trinity can be summarized in four biblical truths.
There is one God.
The Father is God.
The Son is God.
The Holy Spirit is God.
The Father is not the Son.
The Son is not the Holy Spirit.
The Holy Spirit is not the Father.
Yet all three are equally God.
This does not mean Christians worship three gods. Christianity is monotheistic.

One God

Deuteronomy 6:4

"Hear, O Israel: The Lord our God, the Lord is one."

Isaiah 45:5

"I am the Lord, and there is no other."

1 Corinthians 8:4

"There is no God but one."

Throughout Scripture, the Bible consistently teaches that there is only one true God.

Does the Old Testament Hint at the Trinity?

Although the Trinity is revealed most clearly in the New Testament, the Old Testament contains several passages that point toward God's complex unity.
Genesis 1:26

"Let us make mankind in our image..."

God speaks using plural language.
Genesis 3:22

"The man has now become like one of us."

Genesis 11:7

"Come, let us go down..."

Isaiah 6:8

"Whom shall I send? And who will go for us?"

These passages do not fully explain the Trinity, but they prepare us for the fuller revelation found in the New Testament.

Hebrew Words That Suggest Plurality

Several Old Testament passages describe God with plural grammatical forms.
Job 35:10
"My Makers"
Hebrew:
עֹשִׂים (Oseem)
Plural participle meaning "makers."
Psalm 149:2
"Let Israel rejoice in their Makers."
Again, the Hebrew uses a plural form.
These grammatical features do not independently prove the Trinity, but they fit naturally with the later revelation that God exists as Father, Son, and Holy Spirit.

The Father, The Son, and the Holy Spirit

God the Father

The Father is fully God.
Isaiah 64:8
"You, Lord, are our Father."
Matthew 6:9
"Our Father in heaven..."
John 6:27
"The Father has set his seal."
The Father plans salvation, sends the Son, and receives glory.

Jesus is God

The New Testament repeatedly identifies Jesus as fully divine.
John 1:1
"The Word was God."
John 1:14
"The Word became flesh."
John 8:58
"Before Abraham was, I am."
Jesus applies God's covenant name to Himself.
John 10:30
"I and the Father are one."
The Jewish leaders understood this as a claim to deity.
John 20:28
Thomas answered,
"My Lord and my God!"
Jesus accepted this worship.
Colossians 2:9
"In Christ all the fullness of the Deity lives in bodily form."

Jesus Possesses God's Authority

The Bible attributes works to Jesus that belong only to God.
Forgives sins
Mark 2:5–12
Judges the world
John 5:22
Matthew 16:27
Revelation 22:12–13
Receives worship
Matthew 14:33
John 9:38
Created everything
John 1:3
Colossians 1:16–17
Hebrews 1:2

The Holy Spirit is God

The Holy Spirit is not merely God's power.
He is a divine Person.
Acts 5:3–4
Lying to the Holy Spirit is lying to God.
1 Corinthians 3:16
Believers are God's temple because God's Spirit lives in them.
2 Corinthians 3:17
"The Lord is the Spirit."

The Holy Spirit is Personal

The Holy Spirit...
teaches (John 14:26)
speaks (Acts 13:2)
guides (John 16:13)
can be grieved (Ephesians 4:30)
intercedes (Romans 8:26)
gives gifts (1 Corinthians 12:11)
Only a person can do these things.

The Trinity Together

Several passages show the Father, Son, and Holy Spirit together.
Matthew 3:16–17
Jesus is baptized.
The Father speaks.
The Spirit descends.
Matthew 28:19
"Father...
Son...
Holy Spirit..."
One singular "name."
2 Corinthians 13:14
Paul closes with a Trinitarian blessing.

Common Misunderstandings

Does the Trinity mean three gods?

No.
There is one God.
Three Persons.
One divine essence.

Is Jesus the Father?

No.
Jesus prays to the Father.
The Father sends the Son.
They are distinct Persons.

Is the Holy Spirit just God's power?

No.
The Holy Spirit speaks, teaches, guides, and can be grieved.
He is a Person.

Is the Trinity a contradiction?

No.
Christians do not believe:

One God who is three Gods.

Christians believe:

One God in three Persons.

Those are different categories.
God is one in being and three in person.

Why does the Trinity Matter

The Trinity is not merely a theological concept.
It explains the gospel.
The Father sends the Son.
The Son willingly dies for sinners.
The Holy Spirit applies salvation to believers.
Without the Trinity, the gospel itself would be impossible.

God's Love Before Creation

God did not create because He was lonely.
Before creation:
the Father loved the Son (John 17:24)
the Son loved the Father (John 14:31)
the Spirit shared perfect fellowship with them
God has always existed in perfect love.
Creation was not about filling a need.
It was about sharing His goodness.

God Is Truth: Salvation Through Jesus

Salvation Through Jesus

Because Jesus is God, only He could bear the sins of the world.
John 3:16
God loved the world enough to send His Son.
John 14:6
Jesus said,
"I am the way and the truth and the life. No one comes to the Father except through me."
Acts 4:12
"There is salvation in no one else."

Living in God's Truth

If God is truth, then His Word is truth.
2 Timothy 3:16–17
Scripture equips us for every good work.
Hebrews 4:12
God's Word examines our hearts.
John 16:7–8
The Holy Spirit convicts us of sin and leads us toward righteousness.
Following Jesus means surrendering our lives to God's truth rather than creating our own.
