Discovering the Trinity

Devotional

Day 1: Three Witnesses, One Unshakable Truth

The Bible anchors the mystery of the Trinity in tangible witnesses: the Father, the Word, and the Spirit. These three are distinct yet inseparable, like three voices harmonizing as one song. Their unity isn’t a mathematical puzzle but a divine reality woven through Scripture. To deny their oneness is to ignore the chorus of verses declaring God’s triune nature. Yet this truth isn’t meant for debate—it’s a foundation to stand on, even when human understanding falters. [01:19]

“For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.”
(1 John 5:7, KJV)

Reflection: Where have you sensed the distinct roles of the Father, Son, and Spirit working together in your life? How might their unity strengthen your trust in God’s promises?

Day 2: The Spirit’s Voice: More Than a Whisper

The Holy Spirit is not a vague force but a Person who speaks, grieves, and acts. To lie to Him is to lie to God Himself, as Ananias learned. His presence fills believers, making them living temples where divinity dwells. Denying His personhood rejects the God who breathes life into dust and raises the dead. The Spirit’s work in creation, resurrection, and daily guidance proves He is fully God—near, personal, and sovereign. [09:20]

“But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost… thou hast not lied unto men, but unto God.”
(Acts 5:3–4, KJV)

Reflection: When have you recognized the Holy Spirit’s personal presence this week? How might you honor Him as God today?

Day 3: The Word Who Built the World

Before time began, the Word existed—eternal, uncreated, and active. He spoke galaxies into being and shaped humanity from clay. Jesus, the Word made flesh, is no mere prophet or angel. He is the Creator holding atoms together, the eternal “I AM” who stepped into time. To call Him less than God is to erase His fingerprints from the universe and His redemption from the cross. [23:07]

“In the beginning was the Word, and the Word was with God, and the Word was God. All things were made by him; and without him was not any thing made that was made.”
(John 1:1–3, KJV)

Reflection: What part of creation most reminds you of Christ’s power? How does His role as Creator shape your worship?

Day 4: “I AM” in the Flesh

When Jesus declared, “Before Abraham was, I AM,” He claimed the divine name revealed to Moses at the burning bush. The Jews heard blasphemy; believers hear salvation. His eternal nature transcends time, His authority silences death, and His identity as God-in-skin demands surrender. To follow Him is to bow not to a moral teacher, but to the Lord who was, and is, and is to come. [27:48]

“Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.”
(John 8:58, KJV)

Reflection: How does Jesus’ bold claim to divinity challenge your view of His authority? What would it look like to live today in light of His “I AM”?

Day 5: Firstborn Over All, Not First Created

“Firstborn” in Scripture speaks of supremacy, not sequence. Christ reigns over creation not as its first product but as its unrivalled King. Every galaxy, angel, and heartbeat exists by Him and for Him. Heresies shrink Him to a mere creature, but the Word explodes such smallness—He is the fullness of God in flesh, the preeminent Lord who holds all things together. [35:21]

“Who is the image of the invisible God, the firstborn of every creature… For by him were all things created, that are in heaven, and that are in earth… and he is before all things, and by him all things consist.”
(Colossians 1:15–17, KJV)

Reflection: Where have you been tempted to minimize Christ’s supremacy? How might acknowledging His preeminence change your priorities today?

Sermon Summary

First John 5:7 gathers the doctrine into one plain statement: “there are three that bear record in heaven, the Father, the Word, and the Holy Ghost, and these three are one.” The doctrine of the Trinity is not built off one lonely verse, because Bible doctrine does not hang on one nail. The truth shows up when verse after verse points the same direction.

The oneness of God stands first. Isaiah says over and over, “I am the Lord, and there is none else.” Deuteronomy 6:4 says, “The Lord our God is one Lord.” The Trinity is not three gods. The triune God is one God manifest in three distinct persons: the Father, the Word, and the Holy Ghost.

The Father is God, and that point does not take long because Scripture says it plainly and often. The Spirit is God too, though cults often try to make Him an “active force” instead of a person. First Corinthians 3 says the believer is the temple of God, then says the Spirit of God dwells in that temple. Acts 5 says Ananias lied to the Holy Ghost, then says he lied to God. A force cannot be lied to. A force cannot be grieved. The Holy Ghost is personal, and the Holy Ghost is God.

Creation also bears that witness. Genesis says God created, and Job says, “The Spirit of God hath made me.” The resurrection bears the same witness. Scripture says God raised Christ, Christ raised Himself, and the Spirit quickened Him. Those statements are not contradictory. They are complementary, because the Father, Son, and Spirit are one God at work.

The divine attributes make the same case. Omnipresence belongs to Jehovah, yet David asks, “Whither shall I go from thy Spirit?” Eternality belongs to God alone, yet Hebrews speaks of “the eternal Spirit.” The Spirit possesses what only God possesses.

The Son is God just as clearly. John 1 says, “the Word was with God” and “the Word was God.” Jesus is distinct from the Father, yet not less than the Father. John 5 says Jesus made Himself equal with God. John 8 shows Jesus taking the divine name, “I am,” and the Jews understood it well enough to pick up stones.

Colossians does not make Jesus a created being. “Firstborn” means preeminent, first in rank, above all creation. All things were made by Him and for Him, and in Him dwells all the fullness of the Godhead bodily. Hebrews says the Son is the express image of God’s person, purged sins by Himself, sits above angels, and is called “God” by the Father. The submission of Christ does not make Him less God. The Son submits as man to do the Father’s will in the place of sinful men.

Key Takeaways

1. Doctrine rests on many witnesses The Trinity does not stand on one isolated proof text. Scripture teaches by accumulation, with one passage shining light on another until the same truth becomes impossible to honestly dodge. First John 5:7 is not a strange outlier, but a compact statement of truths the whole Bible has already been saying. [00:34]
2. The Spirit is truly personal The Holy Ghost is not treated like power floating around in the air. Scripture speaks of Him as “He,” says He can be lied to, and says He can be grieved. Personhood matters because an impersonal force cannot dwell, testify, seal, grieve, or be sinned against as God Himself. [09:20]
3. Divine works reveal divine identity Creation and resurrection are not small matters that can be handed to a creature. Job says the Spirit made him, and the New Testament places Father, Son, and Spirit at work in raising Christ from the dead. The works that belong to God reveal the God who is doing them. [11:19]
4. Jesus is not less than God John 1 does not leave room for a half-divine Christ or a created Christ. The Word was with God, so the Son is distinct, and the Word was God, so the Son is fully divine. The Son’s distinction from the Father never means inferiority to the Father. [21:57]
5. Christ’s submission is redemptive humility The Son’s obedience to the Father does not prove He is less God. His submission belongs to His real humanity, where He stands in the place of men who failed to do the Father’s will. The equal Son willingly stoops, not because deity is lacking, but because redemption requires a true man to obey.

#JesusSaidIAm

“``What is it called if you take the name of god upon yourself wrongfully? It's blasphemy, right? If I was to say that I am god, I'm a blasphemer. Do you know what the punishment for blasphemy was under the old covenant? You were stoned to death. So, whenever Jesus said before Abraham was and he says, I am and they pick up rocks to throw at him. They knew exactly what he meant. They knew he was making the statement that I am god and they were punishing him for what they believed to be such blasphemy and so, Jesus makes it clear in his own words. He claimed to be god.”

#FullnessInChrist

“For it pleased the father that in him should all fullness dwell. Alright, how much fullness dwells in the son? Oh, now here's the question, fullness of what? Right? Full of what? Paul picks this idea up. Colossians two, look in verse nine. For in him dwelleth all the fullness of what? The godhead bodily. All the fullness of deity that's amongst the godhead, the triune god, the father, the son, the spirit, all divinity that is found in god himself is dwelling fully in the body of Jesus Christ. So, when we read Colossians one fifteen, is Paul making the case that Jesus is a created being or is he making the case that Jesus is preeminent overall created beings? You seem a little hesitant. I'll answer for you. He's making the case. He's preeminent above all created beings.”

#JesusIsCreator

“And it becomes very clear, you cannot get around at verse one that the word was god. Now, once again, eternality is ascribed to the son. Verse two, the same was in the beginning with god. Now, if he was there in the beginning, then that means he had to be existent before the beginning, right? Amen. And so, eternality is ascribed to the son. How about Genesis one one? Yet again, in the beginning, god created the heavens and the earth, right? Who's the creator? Jehovah and yet what does verse three say? All things were made by him. Who's the him? It's the word. It's Jesus, right? All things were made by him and without him was not anything made that was made. And so, Jesus himself is the creator. You say, but wait a minute, I thought god was the creator. Exactly. Exactly.”

#JesusAscribedIAm

“So, Moses said, if I go back, I gotta tell him the name of the god that sent me and god tells Moses what his name is. He said, I am that I am and he said, thus shalt thou say unto the children of Israel, I am has sent me unto you and so when Jesus says in John eight fifty eight before Abraham was, I am, he is ascribing the name of Jehovah directly to himself. He is openly proclaiming that he is god and we know that that's what he meant because that's exactly how the Jews understood him. Notice what they did in verse 59. Then took they up stones to cast at him.”
