John 8:12
KJV - Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
NLT - Jesus spoke to the people once more and said, “I AM the light of the world. If you follow Me, you won’t have to walk in darkness, because you will have the light that leads to life.”
From Matthew Henry's commentary via BibleGateway's "Study This" button:
God is light, and Christ is the image of the invisible God...
The visible light of the world is the sun, and Christ is the Sun of righteousness.
One sun enlightens the whole world, so does one Christ,
and there needs no more.
