He is the beginning !
Col 1:18
18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
This scripture sets forth a profound Mystery and Truth, that Christ as the Head of His Body the Church, was in the beginning, in other words, He existed in this capacity as the Head of the Body, His Church, at the beginning of the World, and it is what is referred to here Rev 3:14
14 And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God;
Prov 8:23
23 I was set up from everlasting, from the beginning, or ever the earth was.
And He was set up the Head of His Body the Church, which are called the Sons of men in Prov 8:31
31 Rejoicing in the habitable part of his earth; and my delights were with the sons of men.
Thats His Church, members of His Body, that He takes delight in, and it is those He made in His Image and Likeness, who are the ones to be conformed to His Image through redemptive blessing Rom 8:29
29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
The Ones Created in His Image Gen 1:26
26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Matt 13:37
37 He answered and said unto them, He that soweth the good seed[offspring, descendants] is the Son of man; See Gen 1:26 !
As the beginning the Head of the Church, He is also the originating cause Eph 3:9
9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
In other words, Creation had an Redemptive Purpose hidden in Christ, it was a Mystery !
It was the redemptive purpose for that world[The Church He is the Head of ] chosen in Him before the foundation Eph 1:4
4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 6
