Four Key Scripture Texts

Christ is the fulfillment of all creation John 1:1-18

In the beginning was the Word: and the Word was with God and the Word was God. He was with God in the beginning.
Through him all things came to be, not one thing had its being but through him.
All that came to be had life in him and that life was the light of men, a light that shines in the dark, a light that darkness could not overpower.
The Word was the true light that enlightens all men; and he was coming into the world.
He was in the world that had its being through him, and the world did not know him.
He came to his own domain and his own people did not accept him.
But to all who did accept him he gave power to become children of God, to all who believe in the name of him
who was born not out of human stock or urge of the flesh or will of man but of God himself.
The Word was made flesh, he lived (tabernacled) among us, and we saw his glory, the glory that is his as the only Son of the Father, full of grace and truth.
Indeed, from his fullness we have, all of us, received - yes, grace in return for grace, since, though the Law was given through Moses, grace and truth have come through Jesus Christ.
No one has ever seen God; it is the only Son, who is nearest to the Father's heart, who has made him known.

Christ is predestined from the beginning  Ephesians 1:3-14

Blessed be the God and Father
of our Lord Jesus Christ,
who has blessed us in Christ
with every spiritual blessing in the heavenly places.
He chose us in him
before the foundation of the world,
that we should be holy and blameless before him.
He destined us in love
to be his sons through Jesus Christ,
according to the purpose of his will,
to the praise of his glorious grace
which he has freely bestowed on us in the Beloved.
In him we have redemption through his blood,
the forgiveness of our trespasses,
according to the riches of his grace
which he has lavished upon us.
He has made known to us
in all wisdom and insight
the mystery of his will,
according to his purpose which he set forth in Christ.
His purpose he set forth in Christ
as a plan for the fullness of time,
to unite all things in him,
things in heaven and things on earth.

Christ is the head of all creation  Colossians 1:15-20

Let us give thanks to the Father, who has qualified us to share in the inheritance of the saints in light.
He has delivered us from the dominion of darkness and transferred us to the kingdom of his beloved Son in whom we have redemption, the forgiveness of our sins.
He is the image of the invisible God, the first-born of creation, for in him all things were created, in heaven and on earth, visible and invisible.
All things were created through him and for him. He is before all things and in him all things hold together.
He is the head of the body, the Church; he is the beginning, the first-born from the dead, that in everything he might be pre-eminent.
For in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross.

God speaks through his Son: through whom he made everything  Hebrews 1:1-4

At various times in the past and in various different ways, God spoke to our ancestors through the prophets; but in our own time, the last days, he has spoken to us through his Son, the Son that he has appointed to inherit everything and through whom he made everything there is.
He is the radiant light of God's glory and the perfect copy of his nature, sustaining the universe by his powerful command; and now that he has destroyed the defilement of sin, he has gone to take his place in heaven at the right hand of divine Majesty.
