Cause-of-Christ
Short answer: When we ask about the cause of Christ, Scripture does not answer with a chain of human events. It answers with the Father. John 1:1-18 opens before creation and before Bethlehem, where the Word already was with God and was God, and it closes with the only Son declaring the Father. The cause of Christ is therefore not a contingency God resorted to after human failure; it is the eternal purpose of the Father to reveal himself and to give life through the Son. The Son does not act on his own initiative but as the sent one, and he returns to the glory he had before the world existed. Every passage in this study keeps that order: the Father as source, the Son as revealer, and the Spirit-empowered church as witness. Get the cause wrong and the gospel becomes a rescue operation bolted onto an unrelated God; get it right and grace is eternal.
Before Bethlehem: the Word already was
The opening line of the Fourth Gospel does not begin with a manger, a prophet, or a promise. It begins with a state of affairs that already existed: John 1:1 says, "In the beginning was the Word, and the Word was with God, and the Word was God." The verb is not came to be but was. Whatever else the prologue does, it refuses to let us think of Jesus as a later addition to the divine story.
That single verse carries two claims that must be held together. The Word was with God, which speaks of distinct persons in relationship, and the Word was God, which speaks of full deity. If we drop the first, we lose the Father-Son fellowship that makes the gospel about love rather than mere power. If we drop the second, we lose the whole basis on which the Son can reveal the invisible God and give life to anyone at all.
Notice how the next verses continue the same logic. All things came into being through him, and apart from him nothing came into being. The Son is not a creature among creatures. He is the one through whom creatures exist. The cause of Christ therefore reaches back before the first day of creation; the Son is not caused by history but is himself the agent of it.
The Father as the source, not a rival
If the Son is God, how can the Father be the cause? The New Testament answers without embarrassment. In 1 Corinthians 8:6, Paul writes that there is one God, the Father, of whom are all things, and one Lord, Jesus Christ, through whom are all things. The prepositions are not accidental. The Father is the source, the one of whom; the Son is the agent, the one through whom. This is not a demotion of the Son but a description of an eternal order within the one God.
Paul does not use this order to diminish Jesus. He uses it to include Jesus in the Shema itself, the daily confession of Israel that God is one. To say one God and one Lord in the same breath is a stunning move. It places the Son inside the identity of the one God rather than beside him as a second deity, and it does so while keeping the Father as the fountainhead.
The practical upshot is that the cause of Christ is not the Son seizing something the Father would not give. It is the Father's own purpose, accomplished through the Son he loves. That is why the gospel can be described as the grace of God rather than merely the mercy of a mediator who intervenes against God's reluctance.
Image, firstborn, and the purpose of creation
Colossians 1:15-20 pushes the same theme into the realm of creation and reconciliation. Paul calls the Son the image of the invisible God, the firstborn of all creation. The word firstborn has been a battleground, but in context it speaks of preeminence and inheritance, not of being the first creature. If Paul meant the Son was created, he contradicts the very sentence that follows, where all things in heaven and on earth are said to be created in him and through him and for him.
That little phrase for him is where the cause of Christ touches everything else. Creation exists for the Son. Not because the Son needed a stage, but because the Father's love for the Son is the ground on which anything else is made at all. The universe is not a neutral container into which Christ was later inserted. It is his from the first moment.
Paul then adds the church to the same sentence. The Son is head of the body, the beginning, the firstborn from the dead, so that in all things he might have the preeminence. The one who created all things is also the one through whom all things are reconciled, having made peace through the blood of his cross. Creation and redemption share a single center.
What Hebrews adds about the Son's role
Hebrews opens by contrasting the past and the present. God, having in the past spoken to the fathers through the prophets at many times and in various ways, has in these last days spoken to us by his Son. The argument is not that the earlier revelation was false but that it was partial and now complete in a person. The cause of Christ includes the fact that the Father chose a Son, not a system, as the final word.
The same opening lines describe the Son as the radiance of God's glory and the very image of his substance, upholding all things by the word of his power. These are not titles of a hired messenger. They describe someone whose existence is intrinsic to God's own being, so that to see the Son is to see the glory of the invisible God. The revelation is personal because the revealer is divine.
Then Hebrews adds the climax: after he had by himself purified us from our sins, he sat down at the right hand of the Majesty on high. The sitting is as important as the purifying. It signals completion. The Son's work is finished, and his position at the Father's right hand keeps the cause of Christ anchored in heaven, not in the shifting currents of religious history.
The glory before the world existed
In John 17:1-5, Jesus prays on the night before his death. Lifting his eyes to heaven, he says, Father, the time has come. Glorify your Son, that your Son may also glorify you. The prayer is a window into the relations of the Trinity at the moment of crisis, and what we see is mutual glorification rather than solitary ambition. The Son's glory is not a prize he grasps; it is a glory he asks the Father to restore.
The Son then speaks of the authority the Father has given him over all flesh, so that he should give eternal life to all whom the Father has given him. The chain of grace runs backwards from our receiving life, to the Son's giving it, to the Father's gift of a people to the Son. Nothing in this chain originates with us. We are the recipients, not the cause.
Then comes the most explicit statement of the Son's eternal existence outside the prologue: Father, glorify me with your own self with the glory which I had with you before the world existed. Whatever the incarnation added, it did not begin the Son's glory. The Father and the Son shared glory before there was a world to see it, and the cross is the path by which that glory is at once revealed and returned.
Why the Son's mind is our pattern
Philippians 2:5-11 turns this theology into an ethical command: Have this in your mind, which was also in Christ Jesus. Paul does not introduce the incarnation as an abstract doctrine but as the shape of Christian humility. Because the Son did not consider equality with God something to be grasped but emptied himself, taking the form of a servant, his people are to count others more significant than themselves. The doctrine of Christ's person produces a pattern of Christ's life.
Paul then traces the movement downward and upward. The Son humbled himself, becoming obedient to the point of death, even death on a cross. Therefore God highly exalted him and gave him the name above every name, so that at the name of Jesus every knee should bow and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. Note where the confession ends. It does not end with the Son's self-exaltation but with the Father's glory.
That final phrase is the whole article in miniature. The cause of Christ is the glory of the Father, and the exaltation of the Son is the means by which that glory is displayed. The Son does not compete with the Father for honor. He receives honor, and in receiving it he directs it back. This is why the New Testament can speak of the Son as Lord without ever dividing God against himself.
The prologue as the whole gospel in miniature
John 1:1-18 is often called the prologue, and the name fits. In eighteen verses it gives us the pre-existence of the Word, the creation of all things through him, the life that is the light of men, the darkness that cannot overcome it, the witness of John the Baptist, the rejection by his own, the welcome given to those who receive him, and the astonishing claim that the Word became flesh and lived among us. The whole Gospel is already here in seed.
The prologue closes on the note that ties the whole article together: No one has seen God at any time. The only born Son, who is in the bosom of the Father, has declared him. The cause of Christ is the Father's self-revelation. The invisible God becomes visible in a Son who is not a temporary messenger but the eternal Word. To see Jesus is not to see a second god but to see the one God, and the reason that is possible is that the Son has always been in the Father's bosom.
That is why the cause of Christ cannot be reduced to any human explanation. He is not the product of a religious impulse, a moral teacher who grew into a legend, or a revolutionary who happened to succeed. He is the eternal Word, sent by the Father, through whom all things were made, who took flesh to give us grace upon grace. The cause is love, and the source is the Father.
Biblical fidelity check
What John 1:1-18 establishes is this: the Word existed before creation, was in relationship with God, was God, was the agent of all creation, and became flesh in Jesus. What it does not establish is a hierarchy of value in which the Son is less divine than the Father. The verse says the Word was God, and the New Testament consistently worships the Son without dividing the one God. Neither does the passage establish that the Son's incarnation was an afterthought; it speaks of grace and truth coming through him as the fulfillment of the law given through Moses, an eternal purpose rather than a divine emergency.
A common misreading treats firstborn in Colossians 1:15 as if it meant the first created thing. That reading is refuted by the very next verse in the same passage, which says all things were created in him and through him and for him. If he created all things, he is not one of the things created. Another misreading pits the God of the Old Testament against a kinder Son, but the prologue insists that no one has seen God at any time and that the Son has declared him, so the Son reveals the same God the prophets spoke of, not a different one.

Frequently asked questions
Does John 1:1 really call Jesus God?
Yes. The Greek clause translated and the Word was God places the word for God before the verb for emphasis, while still distinguishing the Word from the one he was with. If the author had meant merely that the Word was divine in some lesser sense, he chose an odd way to say it, especially since the same Gospel later has Thomas address Jesus as my Lord and my God. The historic church has read the verse as an affirmation of the Son's full deity, and that reading fits the grammar and the surrounding argument.
If the Son is God, why does the New Testament call the Father the one God?
Because the New Testament speaks of order within the one God, not of two Gods. First Corinthians 8:6 gives the pattern: one God, the Father, of whom are all things, and one Lord, Jesus Christ, through whom are all things. The Father is the source and the Son is the agent, yet both are included in the one confession of Israel. Christians have historically described this as the eternal generation of the Son, a term that guards both the Son's deity and his relationship to the Father without making him a creature or a second deity.
How should the cause of Christ change how I live?
Philippians 2 is the clearest answer. Because the Son did not grasp at equality but humbled himself, Paul tells the church to have the same mind. The doctrine is meant to produce humility, not just correct ideas. If the eternal Son became a servant, then his people cannot treat status as something to be seized. At the same time, the confession that Jesus Christ is Lord is not private opinion but the truth every knee will eventually acknowledge, so our lives are to be shaped by allegiance to him in public as well as in private.
