This verse in the King James

King James wording

King James Version

That was the true Light, which lighteth every man that cometh into the world.

THE KEY

The Light does not wait for you to find it; it is already illuminating each person who enters the world.

THE MEANING

The true light reaches you and every person entering the world, bringing things into view. Its illumination is not something a person earns or owns; it meets human life at its beginning.

WHAT THIS UNDOES

The belief that light is reserved for those who have earned access dissolves here: the verse says it reaches every person entering the world.

THE ROOT

φῶς

phōs

GROWS FROM

φωτ-

phōt-

Light, shining.

“lighting” in this verse is phōs. The noun and verb belong to one Greek word family: ⁨φῶς⁩ (phōs, light) and ⁨φωτίζω⁩ (phōtizō, illuminate). “Lighteth” names this Light in action, reaching each person.

ALSO GROWS

phōtizō: To illuminate, give light.

φωτίζω

This is the verb used for “lighteth”: the Light itself becomes illumination at work in each person.

phōtismos: Illumination, giving light.

φωτισμός

This related noun makes the connection between light and the act of bringing something into view explicit.

ἀληθινόν

alēthinon

GROWS FROM

ἀληθ-

alēth-

True, genuine, real.

“true” in this verse is alēthinon. The adjective and the word for truth share the same Greek family: this is not merely a light, but the real one. Its illumination is grounded in truth, so what it reveals is not an illusion.

ALSO GROWS

alētheia: Truth.

ἀλήθεια

The shared word family links the genuine Light with truth.

alēthēs: True, genuine.

ἀληθής

This related adjective echoes the verse’s claim that the Light is the real one.

THE PATTERN

Light comes to people and makes seeing possible; it is received before it is possessed.

And God said, "Let there be light," and there was light.

Genesis 1:3 · SDV“Let there be light” uses the jussive, the grammar of permission: light is spoken into appearance, not described as a human achievement.

For with you is the spring of life; in your light we see light.

Psalm 36:9 · SDVLight is not only what is seen; it is also what makes sight possible.

For God, who said, Light shall shine out of darkness, has shone in our hearts, to give the light of knowing the weight of God in the face of Jesus, the Anointed One.

2 Corinthians 4:6 · SDVThe light that shines in hearts makes knowing possible, extending illumination inward as well as across the world.

THE THREAD

Again then Jesus spoke to them, saying, I am the light of the world; whoever follows me shall never walk in the dark, but shall hold the light of life.

John 8:12 · SDV

Both verses use ⁨φῶς⁩ (phōs, light): the “true Light” that reaches every person is the same light Jesus calls the light of the world. Here its universal reach opens into a path through darkness.
