I would suggest that 'illuminate' is a better word than 'enlighten'.
a. properly, to enlighten, light up, illumine: Thayer
Usage: (a) I light up, illumine, Strong
The source is the Light. Which is the Life (John 1:3).
This is not the knowledge of good and evil. This is the tree of Life.
Light falls upon an object. But the light, itself, is invisible. In a mystery, light encapsulates all the colours of the rainbow, yet it itself cannot be seen.
What is seen is what is illuminated.
His is the Life which illuminates every man, coming into the world.
ην το φως το αληθινον ο φωτιζει παντα ανθρωπον ερχομενον εις τον κοσμον
was the light the true which lighteth every man coming into the world
This is ambiguous and I suggest it was intentionally written so. The statement covers the situation before the manifestation of Christ (every man coming into the world is illuminated) and also after his manifestation (his coming into the world illuminates every man, thereafter).
He is the Light (for his is the Life) which illuminates. What is illuminated is men.
All things were made by him, who is God. For God was the word, John 1:1.
One's own inward capabilities of thought, of spiritual apprehension, of moral awareness, of faculties that are more than mere animal instincts : faculties that combine together to make one's own humanity capable of worship, of adoration.
All this, within, is illuminated.
It shines in one's own apprehension. And shines before other men, who can see what humanity is and what humanity is capable of.
God who made it, shines forth in the humanity he made.
Every man. Even the worst of men. The capacities are still there, however latent.
This is what is illuminated. And that illumination ought to inform one of the source of the light which enlightens.
But men loved darkness.
They preferred another kind of light. A dark light. Because their deeds were evil. So the lesser light ruled the night. And men stumbled in darkness.
Until a witness came to give witness to the light.
He was not that light but came to give witness to the light.
Only a new birth would open the eyes of men to see the Light which was already blazing intensely. To them that believe on his name, is given to become the sons of God.
For with thee is the fountain of life: in thy light shall we see light. [Psalm 36:9 KJV]
