Prophecy of Jesus:
He has eternal existence

Prophecy

But you, Bethlehem Ephrathah, who are small among the clans of Judah, out of you will come forth for Me One to be ruler over Israel One whose origins are of old, from the days of eternity. Micah 5:2

Fulfillment

In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1

In Him was life, and that life was the light of men. John 1:4

“Truly, truly, I tell you,” Jesus declared, “before Abraham was born, I am!” John 8:58

The Son is the image of the invisible God, the firstborn over all creation. For in Him all things were created, things in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities. All things were created through Him and for Him. He is before all things, and in Him all things hold together. And He is the head of the body, the church; He is the beginning and firstborn from among the dead, so that in all things He may have preeminence. For God was pleased to have all His fullness dwell in Him, Colossians 1:15-19
