John 1:5

And the light shineth in darkness.

Now the apostle comes more plainly to the thought that Christ is the light of the world. He is the light that shineth in the darkness, has shone in it as the Word, and who continues to shine. The sun shines in the heavens, but bats and owls that hate the light hide from his rays. So, too, Christ shines, but men who love darkness rather than light, can reject him and abide in darkness.

The darkness comprehended it not.

The sun shines upon the darkness and the darkness disappears, but when John wrote the true Light was shining in the earth and the people in darkness understood it not. Christ, the Light of the world, came to his own and his own received him not. They had eyes and saw not, hence were not enlightened. The difficulty was not that there was not light, but they loved darkness rather than light because their deeds were evil. There is. sad tone running through this and the following verses to verse 14.
