"The Spirit of His Son"
Galatians 4:4—6
“The Spirit of His Son”
One Spirit --- the Father’s --- that filled the Son and now fills you
There is one Spirit, and it is the Father’s; it filled the Son, and now it fills you.
--- The Standing Stone ---
Behind “LORD” in your Bible lies a hidden name --- in the Hebrew it is Yahuah Psalm 83:18**; Yahuah is the Father** Isaiah 63:16**; Yahuah is the only God, beside Him there is no other** Isaiah 45:5**; therefore Yahuah the Father is the only true God, leaving no room for a second or third person** 1 Corinthians 8:6**.**
Part One
The Claim
Galatians 4:4—6 is one of the verses gathered up to argue for three co-equal persons. The reason is simple to see. In three short verses, all three show up by name: Yahuah, His Son, and the Spirit. The argument runs: here they are together, side by side, so here is the three-in-one.
Let the passage speak before we answer it.
Galatians 4:4—6
But when the fulness of the time was come, [Yahuah] sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, [Yahuah] hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
Notice the hidden step. The three-person reading assumes that naming three is the same as proving three co-equal persons. But naming is not the same as leveling. A king, his messenger, and the king’s own breath can all appear in one sentence without becoming three kings. The question is never how many are named. The question is what the verse says each one is, and how they relate. So read it slowly. When you do, the verse turns against the very claim it was called to support.
Part Two
“The Spirit of His Son”
Look first at the one who acts. In both verses there is only one sender. Yahuah “sent forth his Son” in verse 4, and Yahuah “hath sent forth the Spirit of his Son” in verse 6. One hand does the sending. Two things are sent. That alone settles the shape of the passage.
ἐξαποστέλλω
exapostellō (Strong’s G1821)
To send forth, to send away on a commission; to dispatch on an errand.
This is the same verb both times. To send is to give an errand, and the one who gives the errand stands over the one who runs it. Yahushua said it plainly: “neither he that is sent greater than he that sent him” John 13:16. A sender outranks the sent. So the very move offered as proof of equality is the move that builds a ladder: Yahuah over all, the Son sent, the Spirit sent. That is order, not a circle of equals.
And being sent forth proves nothing about being God. This very word --- exapostellō --- is the same word used when the brethren “sent forth Barnabas” Acts 11:22, and when Yahushua told Paul, “I will send thee far hence unto the Gentiles” Acts 22:21. The same sending that moved Barnabas and Paul is the sending in our verse. To be sent forth names a commission, not a nature.
Now look at what is actually placed inside the believer. Paul does not write that Yahuah sent “the Holy Spirit, the third person.” He had every word available to say that, and he did not say it. He wrote that Yahuah sent “the Spirit of his Son.”
πνεῦμα
pneuma (Strong’s G4151)
Breath, wind, the unseen presence and life of a person; spirit.
Hold on to that little word “of.” It does not hand the Son a separate spirit of His own. There is one Spirit, and it is the Father’s --- the Spirit Yahuah calls His own: “I will pour out my spirit,” He says Joel 2:28. It is named “the Spirit of his Son” because it is that same Spirit of Yahuah that rested in the Messiah, now sent out from Him into us. The Father, the Son, and the presence in your heart are not three spirits. There is one Spirit --- the Father’s --- in the Son, and now in you.
And see why this matters. Hand the Son a spirit all His own, separate from the Father’s, and you now have two Spirits where Scripture knows only one. Paul says it flatly: “There is one body, and one Spirit” Ephesians 4:4 --- and the picture was set long before, when Yahuah filled the seventy elders not with seventy spirits but with the one Spirit He took from Moses Numbers 11:17. Splitting that one breath of Yahuah into separate, self-standing spirits is a Greek way of carving up the world, not the way of the Hebrew Scriptures. The text keeps it simple: one Spirit, Yahuah’s, sent through the Son. So the verse reached for to prove a separate Spirit-person instead proves there is only the one Spirit of the Father.
And mark the phrase that frames it all: “when the fulness of the time was come.” That is not a vague right moment. In Yahuah’s reckoning, time is measured against His own word and His prophetic promises; the Father holds “the times… in his own power” Acts 1:7, and long before, Daniel had been shown the very count of weeks “unto the Messiah the Prince” Daniel 9:25 --- the clock was set and running. So when the Son was “made of a woman, made under the law” (the Greek genomenon --- he came to be, was born), it was no accident of history. The eternal, only true God is not made of a woman; but a real man, born of a mother under Torah, could arrive on the Father’s appointed clock. The fulness of the time had come, the prophetic hour had struck, and the promise was fulfilled --- not the unbegun Father stepping out of heaven as a second God, but the Messiah entering history exactly when the word said He would.
Part Three
The Promise That Was Kept
Here is what makes the verse shine once you see it. The indwelling Spirit was never promised as a new, third deity moving in. It was promised as Yahuah’s own presence living inside His people. That promise is old, and it is plain.
Ezekiel 36:27
And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
Notice whose Spirit it is: “my spirit,” says Yahuah. Not another person’s --- His own. Galatians 4:6 is that promise come true. The Father puts His Spirit --- which is the same Spirit that filled the Messiah --- inside the believer. One presence, the Father’s, reaching you through His Son.
And it is the same Spirit at work from the very beginning. In the first creation, Yahuah breathed His own breath into the man:
Genesis 2:7
And [Yahuah] God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
The Father’s own breath made Adam a living soul. Now, in the new creation, that same Spirit of Yahuah --- the Spirit that filled the Messiah --- is breathed into the believer, and it brings not merely life but life everlasting. Yahushua showed it plainly when “he breathed on them, and saith unto them, Receive ye the Holy [Spirit]” John 20:22. One Spirit. Two creations. The breath of life then; the breath of eternal life now --- and it was the Father’s Spirit both times.
Yahushua taught it the same way. He promised the Comforter who “dwelleth with you, and shall be in you” John 14:17 --- and then, in the very next breath, said this:
John 14:18
I will not leave you comfortless: I will come to you.
He sets the coming of the Comforter and His own coming side by side. The Comforter’s arrival is His arrival. A few lines later He widens it to two, not three:
John 14:23
If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
The abode is made by “we” --- the Father and the Son. The indwelling is Yahuah and Yahushua, by the Spirit. There is no third resident named. The Comforter is how the Father and the Son live in you.
And Paul makes the whole thing self-defeating for the three-person reading. In one short stretch he calls the very same Spirit by three names --- yet it stays one Spirit, the Father’s:
• the “Spirit of God” --- it is the Father’s Spirit;
• the “Spirit of [Messiah]” --- the same Spirit, named for the One it filled;
• and “[Messiah] in you” --- that Spirit makes the Messiah present in you.
Romans 8:9—10
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of [Messiah], he is none of his. And if [Messiah] be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
Read it again. These are not three spirits, and not a separate third person. They are one Spirit --- Yahuah’s --- named for the Father whose it is, for the Son it filled, and for its work of putting the Messiah within you. You can only speak this way if there is one Spirit, the Father’s, reaching into the heart through His Son.
Conclusion
The Verdict
So follow the arrows. The Father sends. The Son is sent --- born of a woman, under the Law, to redeem. Then the Spirit is sent --- the one Spirit of Yahuah, the same Spirit that filled the Son --- into the heart. And what does that Spirit do once it arrives? It does not point to itself. It cries out one word: “Abba, Father.”
Every movement in this passage runs in one direction and lands in one place --- at the feet of the only Father there is. A verse that ends with the whole heart crying “Abba” was never a portrait of three equals. It is the one Yahuah, working through His Son and living in His people by His one Spirit.
There is one Spirit, and it is the Father’s --- it filled the Son, and now it fills you.
